Arm64: fix VecPredToBoolean code generation for SVE
This patch fixes code generation for VecPredToBoolean so it updates
conditional flags itself based on its predicate input. Prior to this
patch, code generation for VecPredToBoolean (incorrectly) implicitly
assumed that the conditional flags were always updated by its input
HIR (VecPredWhile) and that it immediately followed that HIR.
