aarch64: Remove redundant checks

The checks for `code == UNEQ || code == LTGT` are unecessary, because
they are already excluded by `aarch64_comparison_operator`

gcc/ChangeLog:

	* config/aarch64/aarch64.md (mov<ALLI_GPF:mode>): Delete
	redundant check.
	(mov<GPF:mode><GPI:mode>cc): Likewise.
	(<neg_not_op><mode>cc): Likewise.
