arm: Convert more MVE builtins to predicate qualifiers

arm: Convert more MVE builtins to predicate qualifiers

This patch covers all builtins that have an HI operand and use the
<mode> iterator, thus we can replace HI whe <MVE_vpred>.

Most of the work of this patch series was carried out while I was
working at STMicroelectronics as a Linaro assignee.
