[llvm-commits] [Review request] Constant folding extractvalue instructions.

[Frits van Bommel]

Similar to the patch I just submitted for insertvalue constant
folding, this one implements constant folding for extractvalue
instructions.
It's a lot shorter because it doesn't need to construct new constants
as much (only undef/zeroinitializer ones, no
ConstantStruct/ConstantArray instances).

Since the patch with the shorter filename won't apply unless you've
applied the insertvalue one first, I also added a version that applies
to a clean trunk :).
