Retune mask <->integer cost for non-AVX512 micro-architecture.

gcc/ChangeLog:

	PR target/96744
	* config/i386/x86-tune-costs.h (struct processor_costs):
	Increase mask <-> integer cost for non AVX512 target to avoid
	spill gpr to mask. Also retune mask <-> integer and
	mask_load/store for skylake_cost.
