Simon Pilgrim 0b9f3912ce [InstCombine] Improve mul(x, pow2) -> shl combine for vector constants 
Refactor getLogBase2Vector into getLogBase2 to accept all scalars/vectors. Generalize from ConstantDataVector to support all constant vectors.

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

Reid Spencer ea8b07ee6b Add test case for testing InstCombine with arbitrary precision integer 
types. These tests mimic the integer test cases in the normal InstCombine
test suite but use "strange" integer bit widths.

Most tests written by Zhou Sheng, a few by me.
