[X86] Add some demanded bits test cases for PDEP with constant mask
The number of ones in the mask for the PDEP determines how many
bits of the other operand are used. If the mask is constant we
can use this to build a mask for SimplifyDemandedBits. This can
be used to replace the extends in the test with anyextend.
