I wonder if it is correct for asan to emit the call without setting RTL
function framework first. The DRAP generation needs function in RTL form, so it
is able to emit DRAP setup.
Let's ask Jakub about asan, if it is possible to move generation of the call
after the function is already expanded to RTL.
