  -----------
  [AArch64] Improve code generation for experimental.cttz.elts (#91505)

This patch extends support for lowering the experimental.cttz.elts
intrinsic to BRKB + CNTP instruction sequences, using this lowering for
all legal predicate types. An unused parameter is also removed from some
of the related regression tests.
