[turbofan] Enable complex memory operands for floating-point binop on x64
With this change, a load from memory into a register can be replaced by a memory operand for floating point binops if possible. This eliminates one instruction for following pattern: vmovss xmm0, m32 vmulss xmm1, xmm1, xmm0 ===> vmulss xmm1, xmm1, m32 Change-Id: I6944287fae3b7756621fb6b3d0b3db9e0beaf080 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2411696 Commit-Queue: Fanchen Kong <fanchen.kong@intel.com> Reviewed-by: Bill Budge <bbudge@chromium.org> Reviewed-by: Andreas Haas <ahaas@chromium.org> Cr-Commit-Position: refs/heads/master@{#70255}
