Haojian Wu bf890dcb0f [clang] Don't emit "no member" diagnostic if the lookup fails on an invalid record decl.
The "no member" diagnostic is likely bogus.

Douglas Gregor ed2540d205 When we complain about a member being inaccessible due to a constraint
along an access path, add another note pointing at the member we
actually found.

John McCall 3155f573f5 Turn access control on by default in -cc1.
Remove -faccess-control from -cc1; add -fno-access-control.
Make the driver pass -fno-access-control by default.
Update a bunch of tests to be correct under access control.

John McCall a332b953e8 When elevating access along an inheritance path, initialize the computed
access to the (elevated) access of the accessed declaration, if applicable,
rather than plunking that access onto the end after we've calculated the
inheritance access.

Also, being a friend of a derived class gives you public access to its
members (subject to later modification by further inheritance);  it does
not simply ignore a single location of restricted inheritance.

Also, when computing the best unprivileged path to a subobject, preserve
the information that the worst path might be AS_none (forbidden) rather
than a minimum of AS_private.

John McCall 85f9055955 When pretty-printing tag types, only print the tag if we're in C (and
therefore not creating ElaboratedTypes, which are still pretty-printed
with the written tag).

Most of these testcase changes were done by script, so don't feel too
sorry for my fingers.

John McCall 5b0829a321 Improve access control diagnostics. Perform access control on member-pointer
conversions.  Fix an access-control bug where privileges were not considered
at intermediate points along the inheritance path.  Prepare for friends.

Eli Friedman 7827520ce8 Initialization improvements: addition of string initialization and a few
small bug fixes in SemaInit, switch over SemaDecl to use it more often, and
change a bunch of diagnostics which are different with the new initialization
code.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Anders Carlsson 5879fbd933 Disable access control by default. It can be enabled with the -faccess-control option. When we have better support for it, we can enable it by default again.

Anders Carlsson af06b977f9 It is OK to cast to a private base class if the current member belongs to the class that the private base class is a base of:
class A {};
class B : private A {
  void f(B *b) { A* a = b; }
};

Anders Carlsson 733d77f1b4 Implement checking for base class access. Right now it's overly conservative but that will change. (Also, protected isn't implemented right now).
