Brian Gesiak ee1fc77541 [Analysis] Support bitreverse in -demanded-bits pass ... Summary: * Add a bitreverse case in the demanded bits analysis pass. * Add tests for the bitreverse (and bswap) intrinsic in the demanded bits pass. * Add a test case to the BDCE tests: that manipulations to high-order bits are eliminated once the bits are reversed and then right-shifted.
