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.
