hipe_tagscheme: Improve fixnum add on x86
With the introduction of immediate adds encoded as 'LEA' on x86, it is
now possible to do a fixnum add in two instructions and one branch by
commuting the addition and reusing the result register as a temporary,
which makes the 'alub' a 2-address add, saving a move instruction.
