arm: MVE: Cleanup vcmpne/vcmpeq builtins

After the previous patch, we no longer need to emit the unsigned
variants of vcmpneq/vcmpeqq. This patch removes them as well as the
corresponding iterator entries.

2021-05-10  Christophe Lyon  <christophe.lyon@linaro.org>

	gcc/
	* config/arm/arm_mve_builtins.def (vcmpneq_u): Remove.
	(vcmpneq_n_u): Likewise.
	(vcmpeqq_u,): Likewise.
	(vcmpeqq_n_u): Likewise.
	* config/arm/iterators.md (supf): Remove VCMPNEQ_U, VCMPEQQ_U,
	VCMPEQQ_N_U and VCMPNEQ_N_U.
	* config/arm/mve.md (mve_vcmpneq): Remove <supf> iteration.
	(mve_vcmpeqq_n): Likewise.
	(mve_vcmpeqq): Likewise.
	(mve_vcmpneq_n): Likewise.
