replaceInChain()

SDValue replaceInChain ( SelectionDAG * CurDAG, SDValue Chain, SDValue Old, SDValue New )

static

Given a chain return a new chain where any appearance of Old is replaced by New.

There must be at most one instruction between Old and Chain and this instruction must be a TokenFactor. Returns an empty SDValue if these conditions don't hold.
