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.

Handle Octeon 3 not supporting MIPS paired-single instructions.
The Octeon 3 processor does not support the MIPS paired-single
instructions. This results in illegal instruction errors in the
testsuite when vectorization tests try to use those instructions.
This patch teaches the compiler about that lack of support, so that
warnings are given when -mpaired-single (or something implying it) is
used when compiling for such a processor. I chose to test
TARGET_OCTEON as the simplest conditional; since the older Octeon
processors don't support hard float at all, I don't think the choice
matters for them. Tests that then failed with the warning were
updated to disable them for Octeon.
Tested with no regressions for cross to mips64el-linux-gnu (Octeon
3).
