Richard Sandiford 374a0e50c4 Handle (shl (anyext (shr ...))) in SimpilfyDemandedBits
This is really an extension of the current (shl (shr ...)) -> shl optimization.
The main difference is that certain upper bits must also not be demanded.

The motivating examples are the first two in the testcase, which occur
in llvmpipe output.
