This fixes PR21587, what r221933 fixed for regular programs is now also fixed for decls coming from PCH files. Use another bit from the count/bits uint16_t for storing the "more than one decl" bit. This reduces the number of bits for the count from 14 to 13. The selector with the most overloads in Cocoa.h has ~55 overloads, so 13 bits should still be plenty. Since this changes the meaning of a serialized bit pattern, also increase clang::serialization::VERSION_MAJOR. Storing the "more than one decl" state of only the first overload isn't quite correct, but Sema::AreMultipleMethodsInGlobalPool() currently only looks at the state of the first overload so it's good enough for now. llvm-svn: 224892
