The movl instruction will use emit_rex_32, which will emit a REX prefix without the REX.W bit set. If none of the flags in the REX prefix is needed, emit_rex_32 will not emit a prefix. The mov_w instruction (if it is ever needed) will need to use both the size override prefix and possibly a REX without REX.W set.
