mjit.c: handle memory allocation failure
which was missing in r64033. Prior to r64033, memory allocation failure had been checked by TRY_WITH_GC and handled by rb_memerror. But calling rb_memerror on MJIT worker is problematic since it does EC_JUMP_TAG in the end. Threads except Ruby's main thread must not use it. mjit_compile.c: ditto git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
