Junyang Shao	86b4fe31d9	[dev.simd] cmd/compile: add masked merging ops and optimizations ... This CL generates optimizations for masked variant of AVX512 instructions for patterns: x.Op(y).Merge(z, mask) => OpMasked(z, x, y mask), where OpMasked is resultInArg0.

Junyang Shao	771a1dc216	[dev.simd] cmd/compile: add peepholes for all masked ops and bug fixes ... For 512-bits they are unchanged. This CL adds the optimization rules for 128/256-bits under feature check. This CL also fixed a bug for masked load variant of instructions and make them zeroing by default as well.
