When calling a function without a prototype for which we have a
...
definition, warn if there are too many/too few function call
arguments.

Make sure to use RequireCompleteType rather than testing for

incomplete types. RequireCompleteType is needed when the type may be
completed by instantiating a template.

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"

Handle any undeclared parameters in a K&R-style function with a
...
special action, inside function prototype scope. This avoids confusion
when we try to inject these parameters into the scope of the function
body before the function itself has been added to the surrounding
scope. Fixes <rdar://problem/6097326>.
