Log:
Allocate memory on cache line if requested

Since GTM::gtm_thread has

gtm_thread *next_thread __attribute__((__aligned__(HW_CACHELINE_SIZE)));

GTM::gtm_thread::operator new () calls xmalloc with separate_cl == true.
xmalloc must return memory on cache line in this case.

	PR libitm/70456
	* util.cc (xmalloc): Use posix_memalign to allocate memory on
	on cache line if requested.
