Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.

Douglas Gregor d6b05f705b Tighten up the determination of whether a function declaration has a
prototype. Thanks Eli!

Douglas Gregor 3729f240af If a function is declared as, e.g.,
F f;

where F is a typedef of a function type, then the function "f" has a
prototype. This is a slight tweak to Chris's suggested fix in
PR3817. Fixes PR3817 and PR3840.

Douglas Gregor a74a29771f Implement GNU C semantics for K&R function definitions that follow a
prototype of the same function, where the promoted parameter types in
the K&R definition are not compatible with the types in the
prototype. Fixes PR2821.

Douglas Gregor 5a80bd1504 Rework the way we find locally-scoped external declarations when we
need them to evaluate redeclarations or call a function that hasn't
already been declared. We now keep a DenseMap of these locally-scoped
declarations so that they are not visible but can be quickly found,
e.g., when we're looking for previous declarations or before we go
ahead and implicitly declare a function that's being called. Fixes
PR3672.

Douglas Gregor eddf4333fd When we're declaring an object or function with linkage, teach name
lookup to skip over names without linkage. This finishes
<rdar://problem/6127293>.

Douglas Gregor de681d43eb In C, when we see a function declaration within a local scope, export
that declaration to global scope so that it can be found from other
scopes. This allows us to diagnose redeclaration errors for external
declarations across scopes. We also warn when name lookup finds such
an out-of-scope declaration. This is part of <rdar://problem/6127293>;
we'll also need to do the same thing for variables.

Douglas Gregor e62c0a45dd Improve merging of function declarations. Specifically:
- When we are declaring a function in local scope, we can merge with
    a visible declaration from an outer scope if that declaration
    refers to an entity with linkage. This behavior now works in C++
    and properly ignores entities without linkage.
  - Diagnose the use of "static" on a function declaration in local
    scope.
  - Diagnose the declaration of a static function after a non-static
    declaration of the same function.
  - Propagate the storage specifier to a function declaration from a
    prior declaration (PR3425)
  - Don't name-mangle "main"

Douglas Gregor bcbf86399f When a function with a prototype is redeclared without a prototype,
merge the prototype into the redeclaration (and make a note in the
declaration). Fixes PR3588.
