Craig Topper e58cd9cbc6 [X86] Add isel patterns to match BMI/TBMI instructions when lowering has turned the root nodes into one of the flag producing binops. 
This fixes the patterns that have or/and as a root. 'and' is handled differently since thy usually have a CMP wrapped around them.

I had to look for uses of the CF flag because all these nodes have non-standard CF flag behavior. A real or/xor would always clear CF. In practice we shouldn't be using the CF flag from these nodes as far as I know.
