Hmm, I'm not sure that's the right way to go. DWARF-2 also will say
that an eight byte value is in one register. Why put the hacks in
both readers?

By the way, assuming I can find the time (ugh) I'm not done with
LOC_COMPUTED yet. On my list so far:
- Location lists
- Turning locations into better defined objects
- Thus, allowing LOC_COMPUTED to return a non-computed "location"
- Allowing more complex locations, namely DW_OP_piece style.
- Eventually turning on more uses of DW_OP_piece in GCC.
