Tested on i686, x86_64 Darwin, x86_64 Linux,
OK for trunk?

On some targets it seems that ssize_t is not defined by any of the
headers transitively included by <stdio.h>. This leads to a bootstrap
fail when jit is enabled.
The fix proposed here is to include sys/types.h when it is available
since that is where Posix specifies that ssize_t is defined.
gcc/jit/ChangeLog:
* libgccjit.h: Conditionally include <sys/types.h> where it is
available to ensure declaration of ssize_t.
