saulecabrera opened PR #5461 from x64-imm-mem-mov to main:

This change adds support for immediate to memory moves in x64 which are needed by Winch for zeroing local slots.

This change follows the guideline in isa/x64/inst/emit and uses other instructions (immediate to register moves) as a base for the test cases.

The instruction encoding expectation was derived by assembling each instruction and inspecting the assembly with objdump.

Add a comment here perhaps that we don't need always_emit_if_8bit_needed() on the REX flags, because the dst is a memory operand, not a possibly 8-bit register?
