Changed a bunch of fixnum procedures. Fixnums are now shifted 8 bit to
the left before the operations (except multiply, where only one of the
operands is shifted) so that overflow detection gets done
automatically by the hardware.
Also fixed a bug in the fixnum register*register rule which was
manifested when the two source registers were the same and we could
alias them with the target.
