[PCH] Mark a PCH file with a flag to indicate if the serialized AST had
compiler errors or not.
-Control whether ASTReader should reject such a PCH by a boolean flag at ASTReader's creation time.
By default, such a PCH file will be rejected with an error when trying to load it.
[libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors
occurred.
-Have libclang API calls accept a PCH that had compiler errors.
The general idea is that we want libclang to stay functional even if a PCH had a compiler error.
