C++ PATCH to objc-map.c to fix build with --enable-gather-detailed-mem-stats

[Jason Merrill]

objc-map.c has been calling _stat allocation functions without using 
MEM_STAT_INFO for passing the file location information to the 
allocator, which breaks bootstrap with 
--enable-gather-detailed-mem-stats.  Fixed by calling the non-_stat 
variant instead.

Applying as obvious.

    	* objc-map.c (objc_map_private_resize, objc_map_alloc_ggc): Don't
    	call _stat functions without MEM_STAT_INFO.
