Previously, an invalid instruction like:
foo %r1, %r0
would generate the rather odd error message:
....: error: unknown token in expression
foo %r1, %r0
^
We now get the more informative:
....: error: invalid instruction
foo %r1, %r0
^
The same would happen if an address were used where a register was expected.
We now get "invalid operand for instruction" instead.
