Introduce Twine::toStringRef, a variant of toVector which avoids the copy if the
...
twine can be represented as a single StringRef. Use the new methode to simplify
some twine users.

add new isSingleStringRef()/getSingleStringRef() methods to twine,
...
and use them to avoid a copy of a string in getNameWithPrefix in
the common case. It seems like Value::setName and other places
should use this as well?

Twines: Support numeric conversion directly (uitostr, etc).
...
- Provides static constructors for doing number to string conversions without
using temporaries.
- There are several ways to do this, I think given the Twine constraints this
is the simplest one.
- One FIXME for fast number -> hex conversion.
- Added another comment on one last major bit of perf work Twines need, which
is to make raw_svector_ostream more efficient.
