[clang] Improve Serialization/Imporing/Dumping of APValues
Changes: - initializer expressions of constexpr variable are now wraped in a ConstantExpr. this is mainly used for testing purposes. the old caching system has not yet been removed. - Add all the missing Serialization and Importing for APValue. - Improve dumping of APValue when ASTContext isn't available. - Cleanup leftover from last patch. - Add Tests for Import and serialization. Differential Revision: https://reviews.llvm.org/D63640
