[AArch64] Add a new CC mode for SVE conditions
The SVE ACLE patches need to introduce a new CC_NZC mode for the
conditions that can be tested after a PTRUE. In particular, LT needs
to map to "mi"/"first" and GE to "pl"/"nfrst", instead of the normal
CC mapping.
Another advantage of using a separate mode is that we can print the SVE
names of the conditions, which makes the output a bit easier to read.
It therefore seems like an independent improvement that can go in now.
The patch also avoids using (compare X (const_int 0)), because that gets
folded away when used with LTU and GEU ("cc"/"last" and "cs"/"nlast").
Just using an unspec should be OK.
The full set of conditions can't be tested without other SVE ACLE patches.

The std::codecvt_utf8 class template is not suitable for UTF-16
conversions because it uses UCS-2 instead. For conversions between UTF-8

codecvt_utf8_utf16<C> must be used.

[Darwin] The need for picsym stubs is dependent on linker used, not OS rev.
For very old toolchains, the compiler generated pic symbol stubs that
provide the necessary indirections. We no longer need this (since xcode
3 era) and it's more efficient for the linker to make one stub when it
knows a symbol is needed that for us to emit them speculatively in every
object.
Our current codegen is making the assumption that a specific OS version
uses a specific linker version - and therefore the presence of support
could be based on the target OS rev. Of course, that's way too simplistic
(most likely bogus for cross-toolchains) and we want to make things explict.
Since we have detection of the linker version, we can use that directly
(A config test for support for stub-less linking might also be feasible
but much more involved).
Finally, should the user wish to generate code that caters for export to
use in an environment with an older toolchain, the generation of stubs
can be forced from the command line.
In addition to the points above, branch islanding and a long branch opt
for PowerPC Darwin has become conflated with the emission of these stubs
(which is confusing, and will be rectified in a following patch).

[objective-c/c++, testsuite, 2/3] Workaround for PR90709.
Use the CF-CFString.h, F-NS*.h proxy headers where needed in the objective-c
testsuite. Make minor adjustments to tests as required, providing that those
do not alter the test intent.

[objective-c/c++, testsuite, 1/3] Workaround for PR90709.
Since we cannot parse the current NeXT headers, because of PR90709 and its
dependents, we have a large amount of testsuite noise for Darwin platforms.
In order to restore the usefulness of the testsuite, we are going add headers
without the modern syntax elements that trigger the bug, and use these for
test runs on newer Darwin.
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.

[openacc] Disable pass_thread_jumps for IFN_UNIQUE
If we compile the openacc testcase with -fopenacc -O2, we run into a SIGSEGV
or assert. The root cause for this is that pass_thread_jumps breaks the
invariant that OACC_FORK and OACC_JOIN mark the start and end of a
single-entry-single-exit region.
Fix this by bailing out when encountering an IFN_UNIQUE in
thread_jumps::profitable_jump_thread_path.
Bootstrapped and reg-tested on x86_64.
Build and reg-tested libgomp on x86_64 with nvptx accelerator.
