that is the case, whenever we use it as a scratch register, save it to R12
first and then restore it after the use.
This is a temporary and truly horrible workaround!

- If there is a dynamic alloca, in the epilogue, restore the value of sp
  using r7 - offset.
- Other bug fixes.

eliminateFrameIndex() is even more complicated if frame ptr is used instead of SP when there are dynamic alloca's.

foldMemoryOperand() cannot fold tMOVrr sp into load / store in thumb mode. tLDRspi / tSTRspi cannot target / store high registers.

- If c does not fit in the offset field, materialize sp + c into a register
  using tADDhirr.
