LOAD_MULTIPLE can be emitted inside of a loop body. We need to WAIT if
that loads targets a register for which a load was not already in-flight
at the start of the loop body.
Technically we only have to emit the wait if the dst reg of a new load
is actually used inside the loop, but that would require separate
tracking of source regs used in the loop and is probably not worth
the effort for now.
