  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

When an unresolved definition is found, check to see if it is only unresolved
because the csretcc was upgraded to the sret param attribute. Such changes
change the function type and lead to unresolved definitions. In such cases, just
cast the function to the type expected by the CallInst. That is, cast to the
version of the function that has the sret param attribute.

used for these functions and that it matches the system definition by
using the appropriate type for the size argument.

Fix initializeConstant, now initializeInt. Fixes major performance
bottleneck.

X == Y || X->DominatedBy(Y) is redundant. Remove the X == Y part.

Fix crasher in makeEqual where getOrInsertNode would add a new constant,
producing an NE relationship between the two members we're trying to make
equal. This now allows us to mark more BBs as unreachable.

Force memcpy to be the 32-bit variant. Since this is only used with
CBE and lli which both target 32-bit machines, this should be okay.
