spilled (if it is not already).
- If LR is spilled, use BL to implement far jumps. LR is not used as a GPR
  in thumb mode so it can be clobbered if it is properly spilled / restored
  in prologue / epilogue.
- If LR is force spilled but no far jump has been emitted, try undo'ing the
  spill by:
  push lr -> delete
  pop pc -> bx lr

PEI is now responsible for adding MaxCallFrameSize to frame size and align the stack. Each target can further adjust the frame size if necessary.

this makes it possible for ldr instructions with non-zero immediate

llvm-svn: 29103

use raddr for the ldr instruction. This removes a dummy mov from the assembly output
remove SelectFrameIndex
remove isLoadFromStackSlot
remove isStoreToStackSlot
