* f-lang.c (allocate_saved_bf_node, allocate_saved_function_node,

allocate_saved_f77_common_node, allocate_common_entry_node,
	add_common_block): Use xmalloc rather than malloc, some of which
	were unchecked.
	* gnu-regex.c: At same point as other gdb specific changes
	#undef malloc and then #define it to xmalloc.
	* ch-exp.c (growbuf_by_size): Use xmalloc/xrealloc rather than
	bare unchecked calls to malloc/realloc.
	* stabsread.c (dbx_lookup_type): Use xmalloc rather than bare
 	unchecked call to malloc.
