Re-enable "[MachineCopyPropagation] Extend pass to do COPY source forwarding"

Browse Source 
Issues addressed since original review:
- Moved removal of dead instructions found by
  LiveIntervals::shrinkToUses() outside of loop iterating over
  instructions to avoid instructions being deleted while pointed to by
  iterator.
- Fixed ARMLoadStoreOptimizer bug exposed by this change in r311907.
- The pass no longer forwards COPYs to physical register uses, since
  doing so can break code that implicitly relies on the physical
  register number of the use.
- The pass no longer forwards COPYs to undef uses, since doing so
  can break the machine verifier by creating LiveRanges that don't
  end on a use (since the undef operand is not considered a use).

  [MachineCopyPropagation] Extend pass to do COPY source forwarding

  This change extends MachineCopyPropagation to do COPY source forwarding.

  This change also extends the MachineCopyPropagation pass to be able to
  be run during register allocation, after physical registers have been
  assigned, but before the virtual registers have been re-written, which
  allows it to remove virtual register COPY LiveIntervals that become dead
  through the forwarding of all of their uses.

//
//===----------------------------------------------------------------------===//
//
// This is an extremely simple MachineInstr-level copy propagation pass.
// This is a simple MachineInstr-level copy forwarding pass. It may be run at
// two places in the codegen pipeline:
// - After register allocation but before virtual registers have been remapped
// to physical registers.
// - After physical register remapping.
//
// The optimizations done vary slightly based on whether virtual registers are
// still present. In both cases, this pass forwards the source of COPYs to the
// users of their destinations when doing so is legal. For example:
//
// %vreg1 = COPY %vreg0
// ...
// ... = OP %vreg1
//
// If
// - the physical register assigned to %vreg0 has not been clobbered by the
// time of the use of %vreg1
// - the register class constraints are satisfied
// - the COPY def is the only value that reaches OP
// then this pass replaces the above with:
//
// %vreg1 = COPY %vreg0
// ...
// ... = OP %vreg0
//
// and updates the relevant state required by VirtRegMap (e.g. LiveIntervals).
// COPYs whose LiveIntervals become dead as a result of this forwarding (i.e. if
// all uses of %vreg1 are changed to %vreg0) are removed.
//
// When being run with only physical registers, this pass will also remove some
// redundant COPYs. For example:
//
// %R1 = COPY %R0
// ... // No clobber of %R1
// %R0 = COPY %R1 <<< Removed
//
// or
//
// %R1 = COPY %R0
// ... // No clobber of %R0
// %R1 = COPY %R0 <<< Removed
//
