  Log Message:
  -----------
  [AArch64][SVE] Add PTEST_ANY pseudo instruction

This allow recognition of when a ptest was emitted as an any condition
and allows for extra optimization to be done later.

This addresses missing optimizations from D137716 and D137718, and
partially D137717.

Depends on D137716, D137717, D137718
