// phielim eliminates redundant phi values from f.
// A phi is redundant if its arguments are all equal. For
// purposes of counting, ignore the phi itself. Both of
// these phis are redundant:
//
//	v = phi(x,x,x)
//	v = phi(x,v,x,v)
//
// We repeat this process to also catch situations like:
//
//	v = phi(x, phi(x, x), phi(x, v))
//
// TODO: Can we also simplify cases like:
//

	// Adjust c.Preds
	c.removePred(j)

	// Remove phi args from c's phis.
	for _, v := range c.Values {

		// Note: this is trickier than it looks. Replacing
		// a Phi with a Copy can in general cause problems because
		// Phi and Copy don't have exactly the same semantics.
		// Phi arguments always come from a predecessor block,

//  1. The start memory state of a block is InitMem, a Phi node of type mem or
//     an incoming memory value.
//  2. The start memory state of a block is consistent with the end memory state
//     of its parent nodes. If the start memory state of a block is a Phi value,
//     then the end memory state of its parent nodes is consistent with the
//     corresponding argument value of the Phi node.
