  Log Message:
  [X86] combinePTESTCC - remove unnecessary legal vector type assertion

Most of these folds bitcast to the PTEST operand type anyway, and its only relevant for the PTEST->MOVMSK fold, which I'm looking at expanding to attempt to fold to PTEST->TESTP as well.

Noticed while beginning triage of Issue #60007
