Use separate builtins for signed / unsigned arithmetic. (#3892)

Browse Source 
Per offline discussion with chandlerc and jonmeow, use different
builtins for signed versus unsigned integer ops instead of looking at
the type. In this commit, the arithmetic builtins (add, sub, negate,
mul, div, mod) are split. I'll apply the same change to comparisons and
to right shift in separate PRs.
