Is len guaranteed to be a multiple of mmsize/8? Otherwise this would
cause misalignment. It will also break if len < mmsize/2.

Also if you want a 32-bit result from lea it should be written as "lea
lend, [lenq*8 - mmsize*4]" which is equivalent but has a shorter
opcode (e.g. always use native sizes within brackets).
