Hi,

the attached patch replaces gfc_getmem with calls to xcalloc (from
libiberty). Apart from reducing duplicated code, calloc is better than
malloc + memset, as the allocator knows that the kernel always gives
out zeroed pages so in some cases it can avoid memset'in the area.

Regtested on x86_64-unknown-linux-gnu, Ok for trunk?
