Absolute or relative PC?

Fair enough, though we don't really know the absolute PC at assembly time,
as we're all position independent. Thinking further, having the getpc
opcode take an offset would let us do something like:
getpc I0, FOO
to put the absolute address of FOO into I0, suitable for jumps and jsrs.
