[PATCH v2 4/5] aarch64: Add `aarch64_comparison_operator_cc`

[Karl Meakin via Sourceware Forge]

From: Karl Meakin <karl.meakin@arm.com>

Deduplicate the checks against `ccmode` by extracting to a new
predicate.

gcc/ChangeLog:

	* config/aarch64/aarch64.md(mov<ALLI_GPF:mode>cc): Use new predicate.
	(mov<GPF:mode><GPI:mode>cc): Likewise.
	(<neg_not_op><mode>cc): Likewise.
	* config/aarch64/predicates.md (aarch64_comparison_operator_cc):
	New predicate.
