compiler/arm/insts: Fix COMPUTE-LRA to allow backwards labels.
* COMPUTE-LRA can, under some circumstances, be passed a label
that exists earlier in the instruction stream, rather than the
more usual later in the instruction stream. In such cases, we
need to use SUB instead of ADD, because ADD doesn't allow negative
immediate values.
