Juergen Ributzka fe08a38a2c [X86] Prevent the creation of redundant ops for sadd and ssub with overflow. ... This commit teaches the X86 backend to create the same X86 instructions when it lowers an sadd/ssub with overflow intrinsic and a conditional branch that uses that overflow result. This allows SelectionDAG to recognize and remove one of the redundant operations. This fixes <rdar://problem/15874016> and <rdar://problem/15661073>.
