  [AArch64][SVE] Add PTEST_FIRST pseudo instruction (#157489)

The pseudo is created when the condition of a ptest is FIRST_ACTIVE.

This allows optimizePTestInstr to be extended to handle whilecc intrinsics
that return a predicate pair, where it is necessary to identify the
condition code used to remove a ptest on the first result of the pair.
