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.

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

Since inline_secondary_memory_needed has

  /* ??? This is a lie.  We do have moves between mmx/general, and for
     mmx/sse2.  But by saying we need secondary memory we discourage the
     register allocator from using the mmx registers unless needed.  */
  if (MMX_CLASS_P (class1) != MMX_CLASS_P (class2))
    return true;

moves between MMX and non-MMX units require secondary memory.   There
is no need to check moves between MMX and integer units.

struct processor_costs has:

  const int mmxsse_to_integer;  /* cost of moving mmxsse register to
                                   integer.  */
  const int ssemmx_to_integer;  /* cost of moving integer to mmxsse register. */

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).

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.

	* gcc.dg/darwin-minversion-1.c: Use compile rather than link/run.
	* gcc.dg/darwin-minversion-2.c: Likewise.
