David Majnemer 9e1f653e2f LICM: Don't crash when an instruction is used by an unreachable BB ... Summary: BBs might contain non-LCSSA'd values after the LCSSA pass is run if they are unreachable from the entry block. Normally, the users of the instruction would be PHIs but the unreachable BBs have normal users; rewrite their uses to be undef values. An alternative fix could involve fixing this at LCSSA but that would require this invariant to hold after subsequent transforms. If a BB created an unreachable block, they would be in violation of this. This fixes PR19798.
