/* This caused an ICE during register spilling when targeting thumb.

   There are 8 registers available for arithmetic operations (r0-r7)

   r7 is the frame pointer, and r0-r3 are used to pass arguments.

   Combine was extending the lives of the arguments (in r0-r3) up until the

   call to z. This leaves only 3 regs free which isn't enough to preform the

   doubleword addition.  */
