Peter Collingbourne 8d5e4e48bc GVN: If a branch has two identical successors, we cannot declare either dead. ...

This previously caused miscompilations as a result of phi nodes receiving
undef incoming values from blocks dominated by such successors.

LoopUnswitch.cpp

This change fixes three bugs in loop unswitching. This change causes an 81% speed-up on a benchmark that is based on EigenConvolutionKernel2D from Eigen3, where the lack of loop unswitching blocks hoisting of loads out of a nested loop (see bug 23816 for how loop unswitching and load hoisting are related).
