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

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

Previously, .rodata was hardcoded.  For C++ vague linkage functions,

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.
