[PATCH] [i386] GLC tuning: Break false dependency for dest register.

From: wwwhhhyyy Hi, For GoldenCove micro-architecture, force insert zero-idiom in asm template to break false dependency of dest register for several insns. The related insns are: VPERM/D/Q/PS/PD VRANGEPD/PS/SD/SS VGETMANTSS/SD/SH VGETMANDPS/PD - mem version only VPMULLQ VFMULCSH/PH VFCMULCSH/
