Fix tests that fail without PCH

The recent change to stop transitively including <string> broke some
tests, but only when the library is configured without PCH, because
otherwise the <string> header still gets included via the precompiled
<bits/stdc++.h> header.

for std::string.

[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, 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.

[openacc] Disable pass_thread_jumps for IFN_UNIQUE

If we compile the openacc testcase with -fopenacc -O2, we run into a SIGSEGV

Darwin, Driver - 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, testsuite - Fix pr71694 fail for m32.

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 - Adjust two tests that fail on newer OS versions.
