FYI, I'm pretty sure this patch is wrong. The case which I believe it
gets wrong involves a bundle containing a readonly call which is not
guaranteed to return. (i.e. may contain an infinite loop) If I'm
reading the code correctly, it may reorder such a call earlier in the
basic block - including reordering of two such calls in the process.
This is the same bug which existed in D118538 which is why I noticed it.
If this case isn't possible for some reason, please add test coverage
and clarify comments as to why.
