[LLVMdev] get basic blocks inside a loop

[Michael Ilseman]

Whenever I was tying to do that (in version 2.8), it didn't give them
to me in a topological order. What I did, as a hack-ish temporary
measure, was rely on Function's ordering, and just iterated over all
the blocks in the function, checking to see if the loop contains that
block. Not at all ideal, and what I was writing later evolved to not
need the topological ordering constraint, so I never revisited the
problem. In hindsight, I don't even know if Function guarantees that
they are presented in a topological order, but it always happened to
be the case for me.
