812f4b123e The "gcc.dg/compat/vector-1 -m32" test was broken after the MMX rewrite. The 
function parameters weren't converted to use the correct type (x86_mmx). Add a
check, similar to the one in llvm-gcc, to see if we need the x86_mmx type for
that function parameter. If so, it coerces the type to be that.

622581b73b Revert r116656, "IRgen/Obj-C/NeXT: Fix the IR signature for 
objc_exception_rethrow, so we don't...", since something is actually trying to
call this with the wrong signature (!). Unfortunately I don't understand the new
EH infrastructure well enough to fix it immediately.

a09e8efd1f Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

0077b22aa4 If we're resolving all outstanding fixups, and there are multiple fixups 
for the same destination, then we must potentially rewrite the initial branch
of every fixup.  Without this patch, a short-circuit check meant to prevent
a switch case from being redundantly added was preventing later fixups from
being processed.  Fixes PR8175 (again).
