b43e9c1965 Add support for vicmp/vfcmp codegen, more legalize support coming. 
This is necessary to unbreak the build.

e4fc1ccd4d One real change - don't hoist something that's trivially rematerializable. It's 
possible for it to produce worse code than before.

The rest of this patch is code cleanup.

5c8e8d7fc5 Fix various DOUTs to not call the extremely expensive Value::getName() 
method.  DOUT statements are disabled when assertions are off, but the
side effects of getName() are still evaluated.  Just call getNameSTart,
which is close enough and doesn't cause heap traffic.

9018e836fe For now, abort when an ISD::VAARG is encountered on x86-64, rather 
than silently generate invalid code.

llvm-gcc does not currently use VAArgInst; it lowers va_arg in the
front-end.

43b30a8287 Get exception handling working again on 64 bit 
Darwin.  This is a hack of course, but it does
at least look at the right thing: gotpcrel means
that this is already an offset, so an explicit
offset is not needed (and wrong).  I think this
is good enough for the moment: Anton is working
on something better.

constraint is present" etc.

671fa97a4b Output correct exception handling and frame info 
on x86-64 linux.  This causes no regressions on
32 bit linux and 32 bit ppc.  More tests pass
on 64 bit ppc with no regressions.  I didn't
turn on eh on 64 bit linux because the intrinsics
needed to compile the eh runtime aren't done
yet.  But if you turn it on and link with the
mainline runtime then eh seems to work fine
on x86-64 linux with this patch.  Thanks to
Dale for testing.  The main point of the patch
is that if you output that some object is
encoded using 4 bytes you had better not output
8 bytes for it: the patch makes everything
consistent.

7ebc06bfd8 Yet another nasty spiller bug. 
%ecx = op
store %cl<kill>, (addr)
(addr) = op %al

It's not safe to unfold the last operand and eliminate store even though %cl is marked kill. It's a sub-register use which means one of its super-register(s) may be used below.
