gdb: Use TYPE_LENGTH macro

Browse Source 
Fixes a couple of places where we access the length field of the type
structure directly, rather than using the TYPE_LENGTH macro.

gdb/ChangeLog:

	* i386-tdep.c (i386_mpx_info_bounds): Use TYPE_LENGTH.
	(i386_mpx_set_bounds): Likewise.
	* solib-darwin.c (darwin_load_image_infos): Likewise.
	(darwin_solib_read_all_image_info_addr): Likewise.
