[PATCH v3 07/15] arm: Implement MVE predicates as vectors of booleans

This patch implements support for vectors of booleans to support MVE predicates, instead of HImode. Since the ABI mandates pred16_t (aka uint16_t) to represent predicates in intrinsics prototypes, we introduce a new "predicate" type qualifier so that we can map relevant builtins HImode arguments a
