[PATCH] Allow TestVisitor-based tests to specify use of C++11

[James Dennett]

jdennett added you to the CC list for the revision "Allow TestVisitor-based tests to specify use of C++11".

Hi klimek, chandlerc,

Add enumerators to TestVisitor::Language to allow tests to explicitly specify use of C++98 or C++11.  Lang_CXX is preserved as an alias for Lang_CXX98.

This does not add Lang_CXX1Y or Lang_C11, on the assumption that it's better to add them if/when they are needed.

(This is a prerequisite for a test in a later patch for RecursiveASTVisitor.)
