d9a5b77269 Mark functions in some tests as 'nounwind'. Generating 
EH info for these functions causes the tests to fail for
random reasons (e.g. looking for 'or' or counting lines
with asm-printer; labels count as lines.)

8c1e95810f Use ## for comment delimiter on darwin x86-32, so 
llvm's output .s files will go through gcc -std=c99
without triggering preprocesser errors.  Approach
suggested by Daveed Vandevoorde.

8cb64d8e8b Handle a special case xor undef, undef -> 0. Technically this should be transformed to undef. But this is such a common idiom (misuse) we are going to handle it.

58ad056286 Add CMP32mr and friends to the load-unfolding table. Among 
other things, this allows the scheduler to unfold a load operand
in the 2008-01-08-SchedulerCrash.ll testcase, so it now successfully
clones the comparison to avoid a pushf+popf.

dbdf48276a - SSE4.1 extractfps extracts a f32 into a gr32 register. Very useful! Not. Fix the instruction specification and teaches lowering code to use it only when the only use is a store instruction.

16f62d36e8 implement an initial hack at a straight-line store -> memset optimization. 
This fires dozens of times across spec and multisource, but I don't know
if it actually speeds stuff up.  Hopefully the testers will show something
nice :)

260473f983 Enable support for returning two long-double values in ST(0)/ST(1). 
This allows us to compile fp-stack-2results.ll into:

_test:
	fldz
	fld1
	ret

which returns 1 in ST(0) and 0 in ST(1).  This is needed for x86-64
_Complex long double.

96cdf21ed4 Teach masked value is zero about add and sub, and use MVIZ to 
simplify things like (X & 4) >> 1 == 2  --> (X & 4) == 4.

since it is obvious that the shift doesn't remove any bits.
