FYI,

It's possible to fix this without adding an architecture method, or
implementing location expressions (the penny just dropped). The basic
problem is the same as for the MIPS - need a custom register area. Hence:

- define a sequence of nameless cooked ([NUM_REGS ..
NUM_REGS+NUM_PSEUDO_REGS) range) registers ordered the way stabs would
like them
- modify the existing stabs_regnum_to_regnum to map the messed up
registers onto those values
