Add some simple integer patterns. This allows us to compile this:
...
int %test(int %A) {
%B = add int %A, 1
%C = xor int %B, 123
ret int %C
}
into this:
test:
save -96, %sp, %sp
add %i0, 1, %l0
xor %l0, 123, %i0
restore %g0, %g0, %g0
retl
nop
for example. I guess it would make sense to add reg/reg versions too.
