Good stuff.
CGEN would benefit from improved detection of this sort of error.
If you were to generate a simulator kernel, you'd have been told of
the ambiguity.

Since a real program should not contain junk, a specific choice for
the other variables is not that important.  Go with whatever
working numbers you prefer.  The base-insn-size is the biggie.
