8cf7713753 Extend X86's addFrameReference to add a MachineMemOperand for
the frame reference. This will help post-RA scheduling determine
that spills to distinct stack slots are independent.

4c3a1d8d2b - Rename stackprotector_{prologue,epilogue} to stackprotector_{create,check}.
- Get rid of "HasStackProtector" in MachineFrameInfo.
- Modify intrinsics to tell which are doing what with memory.

b2a4298ce4 Implement the stack protector stack accesses via intrinsics:
- stackprotector_prologue creates a stack object and stores the guard there.

- stackprotector_epilogue reads the stack guard from the stack position created
  by stackprotector_prologue.

- The PrologEpilogInserter was changed to make sure that the stack guard is
  first on the stack frame.
