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

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.

e747d20130 Add more patterns to match in the integer comparison test harnesses.
Fix bugs encountered, mostly due to range matching for immediates;
the CellSPU's 10-bit immediates are sign extended, covering a
larger range of unsigned values.

3d9309c11d Fix live variables issues:
1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue.
2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register:
   = EAX, AX<imp-use,kill>
...
AX =
In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things.
