Hi,
This adds a configure check to libobjc to find out if types of bitfields effect
their layout, and uses it to replace the rather broken usage of
PCC_BITFIELD_TYPE_MATTERS.
bootstrapped + regtested x86_64-linux-gnu, bootstrapped on ppc64le-linux-gnu
and ran check-objc there without failures, and checked the correct part of the
ifdef is used on a cross to m68k-linux-elf. ok? I'm sure I've gotten
something wrong since this is a bunch of auto tools ;-)

libobjc/ChangeLog:
2015-05-01 Trevor Saunders <tbsaunde+...@tbsaunde.org>
* acinclude.m4: Include bitfields.m4.
* config.h.in: Regenerate.
* configure: Likewise.
* configure.ac: Invoke gt_BITFIELD_TYPE_MATTERS.
* encoding.c: Check HAVE_BITFIELD_TYPE_MATTERS.
OK with the general direction here. If Jakub's test is better, then go
with it as a follow-up.
