Support C++ friend declarations for PCH. This commit 'introduces' a slightly different way to restore the state of the AST object. It makes PCHDeclReader/PCHDeclWriter friends and gives them access to the private members of the object. The rationale is to avoid using/modifying the AST interfaces for PCH read/write so that to: -Avoid complications with objects that have side-effects during creation or when using some setters. -Not 'pollute' the AST interface with methods only used by the PCH reader/writer -Allow AST objects to be read-only. llvm-svn: 107219 2010-06-30 06:47:00 +08:00			`// Header for PCH test cxx-friends.cpp`
