John Brawn 23cbf09fad [GVN] Invalidate cached info for phis when setting dead predecessors to undef
When GVN sets the incoming value for a phi to undef because the incoming block
is unreachable it needs to also invalidate the cached info for that phi in
MemoryDependenceAnalysis, otherwise later queries will return stale information.
