Duncan Sands a74a58c83b Teach InstructionSimplify how to look through PHI nodes. Since PHI
nodes can be used in loops, this could result in infinite looping
if there is no recursion limit, so add such a limit.  It is also
used for the SelectInst case because in theory there could be an
infinite loop there too if the basic block is unreachable.
