Guard less code with the JIT mutex
gcc/jit/ChangeLog:
* jit-playback.c (gcc::jit::playback::context::compile): Acquire the
mutex here, immediately before using toplev, and release it here, on
each exit path after acquisition.
(jit_mutex): Move this variable here, from jit-recording.c.
(gcc::jit::playback::context::acquire_mutex): New function, based on
code in jit-recording.c.
(gcc::jit::playback::context::release_mutex): Likewise.
* jit-playback.h (gcc::jit::playback::context::acquire_mutex): New
function.
(gcc::jit::playback::context::release_mutex): New function.
* jit-recording.c (jit_mutex): Move this variable to jit-playback.c.
(gcc::jit::recording::context::compile): Move mutex-handling from
here into jit-playback.c's gcc::jit::playback::context::compile.
* notes.txt: Update to show the new locations of ACQUIRE_MUTEX
and RELEASE_MUTEX.
