compiler: bugfix: wrong immediate op width calculation.
* share/txr/stdlib/compiler.tl (compiler comp-atom): The
calculation which determines whether an integer operand fits
into an immediate move instruction is incorrect.
The width function doesn't include a sign bit, so that
must be counted. Also, the immediate operand includes a two
bit type tag: thus we are off by three.
