//
// This file provides the function:
// AllocaInst* DemoteRegToStack(Instruction& X):
//
// This function takes a virtual register computed by an
// Instruction& X and replaces it with a slot in the stack frame,
// allocated via alloca. It has to:
// (1) Identify all Phi operations that have X as an operand and
// transitively other Phis that use such Phis;
// (2) Store all values merged with X via Phi operations to the stack slot;
// (3) Load the value from the stack slot just before any use of X or any
// of the Phis that were eliminated; and
// (4) Delete X and all the Phis, which should all now be dead.
//
// Returns the pointer to the alloca inserted to create a stack slot for X.
