From: Sergei Trofimovich <siarh...@google.com>
On musl <pthread.h> uses calloc() (via <sched.h>). jit/ includes
it directly and exposes use of poisoned calloc():

In file included from /<<NIX>>/musl-1.2.3-dev/include/pthread.h:30,
from ../../gcc-13-20220626/gcc/jit/jit-playback.cc:44:
/<<NIX>>/musl-1.2.3-dev/include/sched.h:84:7: error: attempt to use
poisoned "calloc"
84 | void *calloc(size_t, size_t);

/<<NIX>>/musl-1.2.3-dev/include/sched.h:124:36: error: attempt to use
poisoned "calloc"
124 | #define CPU_ALLOC(n) ((cpu_set_t *)calloc(1,CPU_ALLOC_SIZE(n)))
| ^
The change moves sys-specific header before "system.h" inclusion
to evade poisoning.

PR c++/106102
* jit-playback.cc: Include <pthread.h> before "system.h" to avoid
calloc()
poisoning.
* jit-recording.cc: Ditto.
* libgccjit.cc: Ditto.
