This commit derives the operand size from `ABI::word_bytes()` in order to zero the given register rather than hardcoding it as a 32-bit size operand. The motivation for this commit is mainly avoiding hardcoding operand sizes in Winch's emission layer where possible, especially in the MacroAssembler.
