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.

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