Benjamin Kramer 2e06b93f43 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.

Daniel Dunbar a91dd9bf5f Twine: Directly support int, long, and long long types. 
- This should resolve Cygwin gcc ambiguities.

Daniel Dunbar e8b3236284 Twine: Provide [u]int{32,64} conversions via implicit constructors instead of 
explicitly.

Daniel Dunbar b49994ad7e 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.
