Using -mno-fdiv gives linker errors unless we build the missing divide
routines in libgcc always.  There is at least one university project
designing RISC-V parts without FP divide that wants to use the option.

	libgcc/
	* config/riscv/t-softfp32 (softfp_extra): Add FP divide routines

This addresses PR 91860 which has four testcases triggering internal errors.
The problem here is that in combine when handling debug insns, we are trying
to substitute
(sign_extend:DI (const_int 8160 [0x1fe0]))
as the value for
(reg:DI 78 [ _9 ])
in the debug insn
(debug_insn 29 28 30 2 (var_location:QI d (subreg:QI (reg:DI 78 [ _9 ]) 0)) "tmp4.c":11:5 -1
     (nil))
This eventually triggers an abort because 8160 is not a sign-extended
QImode value.

In subst there is already code check for a CONST_INT inside a ZERO_EXTEND and
simplify it.  This needs to be extended to also handle a SIGN_EXTEND the same
way.

Shifting by more than the size of a SUBREG_REG doesn't work, so we either
need to disable splits if an input is paradoxical, or else we need to
generate a clean temporary for intermediate results.

Input string consist of four parts:
  <primary arch>-<abi>-<additional arches>-<extensions>

and generator doing combination with <extensions> part, but it just
append the extension at the end of arch string, it might generate
invalid arch.

For example, without this patch `./multilib-generator rv32imafc-ilp32--d`
will generate:

MULTILIB_OPTIONS = march=rv32imafc/march=rv32imafcd mabi=ilp32
                                         ^^^^^^^^^^

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.

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.

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.

This test is failing with older cpus because the included header needs both
altivec and vsx to be enabled to succeed in compiling. Without this (if these
are not defaults for the cpu) there are errors like:

In file included from ... x86intrin.h:41,
from ... bmi2-bzhi64-1a.c:6:
... xmmintrin.h: In function '_mm_loadu_ps':
... xmmintrin.h:122:11:

Fixed by adding -maltivec -mvsx to the options

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.

	* g++.dg/gcov/pr16855.C: Xfail the count lines for the DTORs and the
	"final" line for the failure summaries.  Adjust source layout so that
	dejagnu xfail expressions work.

During GCC-9, the codegen for unreachable switch case statements changed
such that the (undefined) behaviour of reaching such statements is directed
to one of the existing switch cases. This means that the testcase which
deals with the old behaviour can no longer work (and there is nothing to test
with it). The [Darwin-specific] test is now redundant and can be removed.
