After r251146 computeKnownBits() is called multiple times for every instruction in the program, which resulted in a 3% compiletime regression. This patch tries to get some of that compiletime back by optimizing the function:

Put DataLayout reference into the Query structure.
It looks nicer and improves the compiletime of a typical
clang -O3 -emit-llvm run by ~0.6% for me.
