Shouldn't we try to put all the simplification/optimization stuff
into fold_builtin_strchr, then have expand_builtin_strchr and
expand_builtin_strrchr call the folder to simplify/optimize the call?
That would avoid a lot of duplication.

[ And yes, that applies to most of the fold_builtin_XXX stuff I
  added a while back.  Let's start with fixing the simple ones ;-) ]
