For some symbol formats (stabs, for some compilers at least),
the compiler generates two symbols, an argument and a register.

reading, but currently not for all cases (e.g. it's passed on the

frame/stack pointer, rather than the offset from the "canonical
frame address" used by COFF, stabs, etc., and we don't know how
to convert between these until we start examining prologues.
Note that LOC_BASEREG is much less general than a DWARF expression.
We don't need the generality (at least not yet), and storing a general
DWARF expression would presumably take up more space than the existing
scheme. *)
