-Make TokenID of IdentifierInfo read-only, remove setTokenID(). -There are 2 instances that change the TokenID for GNU libstdc++ 4.2 compatibility. To handler those cases introduce a RevertedTokenID bitfield, RevertTokenIDToIdentifier() and hasRevertedTokenIDToIdentifier() methods. Store the bitfield in PCH. llvm-svn: 110868

// Test this without pch.
Implement a new type trait __is_trivially_constructible(T, Args...) that provides the behavior of the C++11 library trait std::is_trivially_constructible<T, Args...>, which can't be implemented purely as a library. Since __is_trivially_constructible can have zero or more arguments, I needed to add Yet Another Type Trait Expression Class, this one handling arbitrary arguments. The next step will be to migrate UnaryTypeTrait and BinaryTypeTrait over to this new, more general TypeTrait class. Fixes the Clang side of <rdar://problem/10895483> / PR12038. llvm-svn: 151352
