This patch adds the x, t and g modifiers for inline asm from GCC. These will print a vector register as xmm*, ymm* or zmm* respectively. I also fixed register names with modifiers with inteldialect so they are no longer printed with a leading %. Patch by Amanieu d'Antras Differential Revision: https://reviews.llvm.org/D78977
