- Used to determine whether the alignment of the type in a bit-field is
respected when laying out structures. The default is true, targets can
override this as needed.
- This is designed to correspond to the PCC_BITFIELD_TYPE_MATTERS macro in
gcc. The AST/Sema implementation only affects one line, unless I have
forgotten something. I'd appreciate further review.
- IRgen still needs to be updated to fully support this (which is effectively
PR5591).

More fallout from r58501: primary fix is some more corrections to make
...
the types for size_t and ptrdiff_t more accurate. I think all of these
are correct, but please compare the defines for __PTRDIFF_TYPE__ and
__SIZE_TYPE__ to gcc to double-check; this particularly applies to
those on BSD variants, since I'm not sure what they do here; I assume
here that they're the same as on Linux.
Fixes wchar_t to be "int", not "unsigned int" (which I think is
correct on everything but Windows).
Fixes ptrdiff_t to be "int" rather than "short" on PIC16; "short" is an
somewhat strange choice because it normally gets promoted, and it's not
consistent with the choice for size_t.

First cut at OS detection, taking advantage of the new generic targets.
...
This approach allows adding OS-specific targets/defines/etc. without
completely breaking unknown subtargets. No new subtargets yet, although
I plan to add x86-Linux soon. Others can add targets that they use as
needed; adding a new subtarget takes very little code.
Also does some fixups for description strings; a lot of them were
unspecified. I think all the ones I added are correct, but
they're unverified; corrections are welcome.
