Craig Topper e81de105a5 [X86] Add patterns to show more failures to use TBM instructions when we're trying to check flags. 
We can probably add patterns to fix some of them. But the ones that use 'and' as their root node emit a X86ISD::CMP node in front of the 'and' and then pattern matching that to 'test' instruction. We can't use a tablegen pattern to fix that because we can't remap the cmp result to the flag output of a TBM instruction.
