Frits van Bommel 28218aa8f1 Transform (extractvalue (load P), ...) to (load (gep P, 0, ...)) if the load has no other uses, shrinking the load.

Frits van Bommel 40a80ac963 Update this test to keep testing the -instcombine transform it's supposed to be testing instead of triggering the improved constant folding for insertvalue and extractvalue.

Dan Gohman 72a13d2476 Use opt -S instead of piping bitcode output through llvm-dis.

Dan Gohman 9737a63ed8 Change these tests to feed the assembly files to opt directly, instead 
of using llvm-as, now that opt supports this.

Matthijs Kooijman f22f34f0cc Add a few cases to instcombine's extractvalue testcase.

Matthijs Kooijman ac5bc8a3dd Make testcase check for extractvalue instead of extractelement.

Matthijs Kooijman b2fc72bfbf Teach instruction combining about the extractvalue. It can succesfully fold 
useless insert-extract chains, similar to how it folds them for vectors.

Add a testcase for this.
