For some Darwin versions the absence of the rethrow_primary_exception

remove the reference to it for all platforms. We do this by adding a

PR c++/90538 - multiple expansions of capture packs
Previously, with init-capture the type of the closure field was a
DECLTYPE_TYPE of the initializer. But since each time we tsubst a lambda we
get a different lambda, that meant that if the initializer is a lambda, we'd
end up with different closure types in the field and initializer after
substitution (PR 87322). We dealt with this by remembering the lambda
instantiation within each pack expansion element, using
local_specialization_stack to separate the elements. But that broke this
testcase, because it lost lambda capture proxies that also use
local_specializations.
So, this patch removes the local_specializations changes from that patch and
fixes 87322 differently, by giving init-capture fields 'auto' type and doing
deduction later. There's a bit of a kludge to get the right number of
fields by pretending that 'auto...' uses the parameter packs from the
initializer, but it does the trick.

Ada, backport push -shared-libgcc where needed.
Gnatlink has code that checks for duplicate '-shared-libgcc’ switches (but not

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,

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.

test a bit more specific for Darwin - that it looks for absence of
branches to local labels.

Darwin, testsuite, backport fix for pr71694.
This test fails for Darwin m32 because it's scanning for absence
of an instruction that's validly used in PIC code. Fixed, in this
case, by using non-PIC codegen.

Darwin, testsuite, backport fix for darwin-minversion-1,2.
Newer OS versions (10.14+) do not provide some of the CRTs that are used
for older ones (e.g. 10.5), and thus link tests that specify targeting
such a revision fail. We retain the testing of the correct defined OS
version number but switch to compile-only testing for these two tests.

Darwin, testsuite, backport fix for cpp0x/alignas4.C
Darwin produces aligned zerofill directives for the objects represented.
We can scan for these using lp64 and ilp32 to catch operation on both
X86 and PowerPC ports (the test is for the alignment which is the trailing
value in the zerofill directive, as a power of two).

Darwin, X86, backport test adjusts for PR90698.
We don't have support for -mcmodel={medium, large, kernel} so don't
expect tests for those things to work.
For now mark them as xfail where possible and skip where that isn't.
These changes will be logged onto the PR and therefore can be backed
out when the facility is implemented.

Darwin, X86, testsuite, backport matching fixes.
Some of the i386.exp tests fail on Darwin (and at least one passes
incorrectly on Linux) because their scan-asm match strings are too
general. In some cases the strings also match instances in the .file
and size directives or in comment output. This patch makes the match
strings more specific.
