Chris Lattner 3c6a0d4ae2 Implement InstCombine:shift.ll:test16, which turns (X >> C1) & C2 != C3 ...

into (X & (C2 << C1)) != (C3 << C1), where the shift may be either left or
right and the compare may be any one.

This triggers 1546 times in 176.gcc alone, as it is a common pattern that
occurs for bitfield accesses.
