S/390: Fix missing .size directives.

It seems at some point the .size hook was hijacked to emit some
machine-specific directives, and the actual .size directive was
forgotten.  This caused problems for split-stack support, since
linker couldn't scan the function body for non-split-stack calls.

to actually emit the .size directive.

S/390: Use proper read-only data section for literals.

Previously, .rodata was hardcoded.  For C++ vague linkage functions,
this resulted in needlessly duplicated literals.  With the new split
stack support, this resulted in link errors, due to .rodata containing
relocations to the discarded text sections.

gcc/ChangeLog:

* config/s390/s390.md (pool_section_start): Use switch_to_section

PR jit/69144: Ensure that libgccjit's tempdir is fully cleaned-up

There were a couple of ways that libgccjit could fail to unlink all
of its tempfiles, leading to /tmp/libgccjit-* tempdirs lingering
after the build:
- dumpfiles requested by gcc_jit_context_enable_dump
- ahead-of-time compilation artifacts which lingered in the tempdir
  after they've been copied up to the output_path.  This was only
  the case for GCC_JIT_OUTPUT_KIND_OBJECT_FILE and
  GCC_JIT_OUTPUT_KIND_EXECUTABLE.

The following patch fixes these by introducing a vec of additional
cleanups to be performed by gcc:jit::tempdir's dtor.

In addition, if a gcc_jit_result * is leaked and
GCC_JIT_BOOL_OPTION_DEBUGINFO is enabled, the tempdir will also
not be cleaned up.  This was the case for tut04-toyvm/toyvm.cc
which the patch fixes by introducing a wrapper around
gcc_jit_result *.  Doing this required some updates to the
corresponding docs.
