Benjamin Kramer 6cceb12d56 [SimplifyCFG] Use the error checking provided by getPrevNode. ...

BasicBlock::size is O(insts), making this loop O(blocks*insts), which
can be really slow on generated code. getPrevNode already checks if
we're at the beginning of the block and returns nullptr if so, just use
that instead. No functionality change intended.
