Reapplies #87541 and #88311 (again) addressing the bug which caused
expressions naming overload sets to be incorrectly rebuilt, as well as
the bug which caused base class members to always be treated as overload
sets.
The primary change since #88311 is `UnresolvedLookupExpr::Create` is called directly in `BuildPossibleImplicitMemberExpr` with `KnownDependent` as `true` (which causes the expression type to be set to `ASTContext::DependentTy`). This ensures that any further semantic analysis involving the type of the potentially implicit class member access expression is deferred until instantiation.
This time, I went with the first approach from
http://reviews.llvm.org/D6700, where clang actually attempts to form an
implicit member reference from an UnresolvedLookupExpr. We know that
there are only two possible outcomes at this point, a DeclRefExpr of the
FieldDecl or an error, but its safer to reuse the existing machinery for
this.

We previously mishandled UnresolvedUsingValueDecls in
NamedDecl::declarationReplaces, which caused us to forget decls
when there are multiple dependent using decls for the same name.
Fixes PR16936.

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.

- 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).

results in them (which we were doing intentionally as a stopgap). Fix
an DeclContext lookup-table ordering problem which was causing UsingDecls to
show up incorrectly when looking for ordinary results. And oh hey
Clang-Code-Syntax passes now.

Also, make the "don't know how to instantiate a particular kind of
declaration" diagnostic nicer, so we don't have to trap Clang in a
debugger to figure out what went wrong.
