Add fast path for raw_ostream output of strings.
- Particularly nice for small constant strings, which get optimized
down nicely. On a synthetic benchmark writing out "hello" in a
loop, this is about 2x faster with gcc and 3x faster with
llvm-gcc. llc on insn-attrtab.bc from 403.gcc is about .5% faster.
- I tried for a fancier solution which wouldn't increase code size as
much (by trying to match constant arrays), but can't quite make it
fly.
