Since we cannot parse the current NeXT headers, because of PR90709 and its

In order to restore the usefulness of the testsuite, we are going add headers

The headers are imported from GNUStep, with some local modifications to make
sure that __BLOCKS__ is honoured as a gate for Apple-style blocks closures.
CF-CFString.h, F-NS*.h are proxy headers that use the installed CoreFoundation
or Foundation headers on systems <= Darwin12 and the GNUStep headers for newer.
Use the CF-CFString.h, F-NS*.h proxy headers where needed in the objective-c

[Darwin, testsuite] Address PR91087 - XFAIL parts of pr16855.C.
The testcase is failing to instrument part of the source because of a bug
in the ordering of static DTORs. It seems unlikely that this is generically
fixable in the toolchain (and given that it's likely to be a dynamic loader
change would not be expected to be applied retrospectively to OS versions
that are out of support). To avoid the testsuite noise, xfail the count lines
that don't match (we can adjust the xfails as/when the upstream bug is fixed).
dejagnu xfails do not seem to work when embedded in a line like:
~Test (void) { .... /* count(1) { xfail ... } */ }
the closing brace seems to confuse the parser. The solution is to exapnd the
text onto three lines.

Gnatlink has code that checks for duplicate '-shared-libgcc’ switches (but not
duplicate ‘static-libgcc’) and also pushes ’static-libgcc' onto the link line for
targets that default to static linking, provided '-shared-libgcc' is not present.
For targets that should use a shared libgcc we need the same process to be
applied (in inverse), in the event that they do not default to providing the
shared flag implicitly.
So this adds the complementary set of tests for the shared case and pushes
the shared flag as needed. As a minor tidy-up there’s no need push duplicates
of the libgcc switch onto the link line when one has already been seen (given by
the user).
The patch does not alter any of the platform defaults for static/shared libgcc,
but it ensures that the intent of the link is explicit.

When we are parsing a source file, the very first token might
be a PRAGMA_GCC_PCH_PREPROCESS. This indicates that we are going
read in a PCH file (named as the value of the pragma). If we don't
see this pragma, then we know that it's OK to release any resources
that the host might have set aside for the PCH file.
There is a thinko in the current implementation, in that the decision
to release resources is happening unconditionally right after the first
token is extracted but before it's been checked or acted upon.
This leads to the pch bug on Darwin, because we actually do release
resources - which are subsequently (reasonably) assumed to be available
when reading a PCH file. We then get random crashes or hangs depending
on the interaction between unmmap and malloc.
The bug is present everywhere but doesn't show on (say) Linux, since
the release of PCH resources is a NOP there.
This effects all the c-family front ends, because they all use
c_lex_with_flags () to implement this.
The solution is to check for the PRAGMA_GCC_PCH_PREPROCESS and only call
c_common_no_more_pch () when that is not the first token.
A secondary effect of the collection is that the name of the PCH file
can be collected during the ggc_pch_read() reset of state. Therefore
we should issue any diagnostic that might name the file before the
collections are triggered.

This is about 32/64b host and multilib support across the range of Darwin
systems.
Prior to Darwin8 (OS X 10.4), the toolchains support only PowerPC and only 32b.
On Darwin8 it is possible to target a 64b multilib, but with support limited
to a few of the main libraries on the system (not a recommended configuration).
From Darwin9 to Darwin17 (OSX 10.5 to 10.13) it is possible to have either
32 or 64b hosted toolchains, with support for a 64 or 32b multilib respectively.
On Darwin9 the kernel is 32b, but with support for 64b executables, so it's
conventional to build a 32b host toolchain supporting a 64b multilib. However
this is not enforced (merely a convention).
There is also some platform hardware supporting Darwin10/11 which is only 32b
and for which the same situation applies. However, from Darwin10 to Darwin17,
the majority of platform hardware supports a 64b kernel and it's conventional
to build a 64b host toolchain with support for a 32b multilib.
On/from Darwin18 (OS X 10.14), the development headers (in the SDK) no longer
expose the interfaces for the 32b multilib support (although sufficient runtime
support remains installed that the testsuite can be run for a 32b multilib).
The PR is raised against this latter situation since the absence of exposed
interfaces causes a 'default' bootstrap fail regardless of the availability of
the runtimes. Given the number of permutations, I felt it warranted a general
solution, especially since the current scheme of target headers and t-make
fragments has become somewhat messy.
The changes here enforce the single 32b PowerPC multilib for Darwin < 8 and the
single X86 64b multilib for Darwin >= 18. This means that there is no longer
any need to configure Darwin18+ '--disable-multilib', but also that if you want
to use the ability to continue to test the compiler's 32b multilib there, you
need to make a configuration targeting an earlier OS version (and using the
SDK from that).

Final check on PCI options; for Darwin these are not dependent on the PIE
ones, although PIE does require PIC to support it. Specifically, for Darwin,
'-fPIC -fno-PIE' should result in the same as '-fno-PIE -fPIC'.
This is a workaround for the situation in which a 'stock-built' GCC is
unable to bootstrap m32 Darwin unless it's done '-mdynamic-no-pic'. So
this fixes a bootstrap fail in that case.

[Darwin, PPC, libgcc] Ensure unwinder is built with altivec enabled.
Fix bootstrap fail when building for 10.4.
When libgcc is built on Darwin, it is usually built for the earliest potential
target (Darwin8, 10.4). Build for that revision default to assuming that the
processor might be G3 (without vector ops) and there is an outlined function
used for save/restore that checks whether the processor is G3 or G4+ at run-
time. However, the unwinder itself needs to be built with the assumption of
vector usage so that the relevant outlined functions are called.

[Darwin, Driver] Fix driver crashes with valid command line input.
Backport Improve processing of macosx-version-min=
For PR target/63810 some improvements were made in the parsing of
the version string at the point it's used to define the built-in
__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__. This is fine, but the
specs processing also uses the version, and specs version-compare
doesn't like leading zeros on components. This means that while we
succeed in processing -mmacosx-version-min=010.00002.000099 on compile
lines, it fails for any other line that uses the value as part of a spec
(in particular, link lines fail).
To fix this, we need to apply a bit of clean-up to the version that's
presented to the driver, and push that back into the command line opts.
The value can come from four places:
1. User-entered on the command line
2. User-entered as MACOSX_DEPLOYMENT_TARGET= environment var.
3. Absent those two
3a For self-hosting systems, look-up from the kernel
3b For cross-compilers, as a default supplied at configure time.
We apply the clean-up to all 4 (although it shouldn't really be needed
for the cases under 3).
We also supply a test-case that adapts to the target-version of the
system, so that the link requirements are met by the SDK in use (if you
try to link i686-darwin9 on an x86-64-darwin18 SDK, it will fail).

[Darwin, fixincludes] Backport fix for Darwin9/10 TR1 test fails.
Darwin has had long long functions for some considerable time and these are
exposed in Darwin8 and Darwin11+ headers. However, for some reason it was
elected to hide them behind __STRICT_ANSI__ and __STDC_VERSION__ on Darwin9
and Darwin10. This is a problem for G++/libstdc++ that expects the functions
to be available for strict ansi (-std=c++14, for example) and without
defining __STDC_VERSION__. The fix here follows the pattern used in
Darwin11+ headers where the functions may be explicitly hidden by defining
__DARWIN_NO_LONG_LONG.
