Dylan McKay 71adee46e4 [AVR] Fix bug which caused assertion errors for some FRMIDX instructions
Previously, if a basic block ended with a FRMIDX instruction, we would
end up doing something like this.

*std::next(MBB.end())

Which would hit an error:

"Assertion `!NodePtr->isKnownSentinel()' failed."
