Richard Smith e87aeb378d When pretty-printing a C++11 literal operator, don't insert whitespace between 
the "" and the suffix; that breaks names such as 'operator""if'. For symmetry,
also remove the space between the 'operator' and the '""'.

Richard Smith 5731c75414 PR12225: The requirement that literal operators be namespace-scope functions 
does not imply that such functions can't be declared at block scope.

Douglas Gregor 86325ad2b5 Allow C99 hexfloats in C++0x mode. This change resolves the standards 
collision between C99 hexfloats and C++0x user-defined literals by
giving C99 hexfloats precedence. Also, warning about user-defined
literals that conflict with hexfloats and those that have names that
are reserved by the implementation. Fixes <rdar://problem/9940194>.

Alexis Hunt 79eb5469e0 Implement C++0x user-defined string literals. 
The extra data stored on user-defined literal Tokens is stored in extra
allocated memory, which is managed by the PreprocessorLexer because there isn't
a better place to put it that makes sure it gets deallocated, but only after
it's used up. My testing has shown no significant slowdown as a result, but
independent testing would be appreciated.

Alexis Hunt c88db06565 Implement semantic checking for C++ literal operators. 
This now rejects literal operators that don't meet the requirements.
Templates are not yet checked for.
