6b543713a2 Rename ComputeMaskedBits to computeKnownBits. "Masked" has been 
inappropriate since it lost its Mask parameter in r154011.

167a57ca45 Add an optimization that does CSE in a group of similar GEPs. 
This optimization merges the common part of a group of GEPs, so we can compute
each pointer address by adding a simple offset to the common part.

The optimization is currently only enabled for the NVPTX backend, where it has
a large payoff on some benchmarks.

Patch by Jingyue Wu.
