alexcrichton opened PR #6058 from x64-more-avx to main:

This PR refactors some gpr-to-xmm-and-back pieces of the x64 backend along with some new AVX instructions, namely:

• The movd and movq instructions now have dedicated helpers with AVX special cases like all other vector-related instructions.
• The mov_rmi_to_xmm function is no longer an auto-conversion between RegMemImm and XmmMemImm since it performs conversions via register moves while all other register-to-register conversions were simply asserting that the register was of the right type.
• AVX lowerings were added for movd, movq, vcvtsi2s{s,d}, and v{,p}movmsk{b,ps,pd}
