Andrea Di Biagio 8e4a223f7b [X86] Add ISel patterns to improve the selection of TZCNT and LZCNT. 
Instructions TZCNT (requires BMI1) and LZCNT (requires LZCNT), always
provide the operand size as output if the input operand is zero.

We can take advantage of this knowledge during instruction selection
stage in order to simplify a few corner case.
