Remove SmallString::append_*int* methods; how many copies of int -> str
conversion code do we really need?
- S.append_uint(N) can be replaced with 'raw_svector_ostream(S) << N' which is
somewhat slower due to the extra set up cost, but still plenty fast
(especially if the svector set up cost can be amortized).
