  Log Message:
  -----------
  [InstCombine] remove dead pattern matching code; NFC

Complexity canonicalization guarantees that a binop and cast
are op0/op1 respectively. Adjusted generic test names to
show that this pattern is still useful.

  Log Message:
  -----------
  [InstCombine] allow matching vector types for icmp-of-mask/cast

Also use a more specific matcher to simplify the mask
compare to type size.
