-// 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.
