Jordan Rose de9e976468 Remove -Winternal-linkage-in-inline in C++.
It's very easy for anonymous external linkage to propagate in C++ through
return types and parameter types. Likewise, it's possible that a template
containing an inline function is only used with parameters that have internal
linkage. Actually diagnosing where the internal linkage comes from is fairly
difficult (both to locate and then to print nicely). Finally, since we only
have one translation unit available, we can't even prove that any of this
violates the ODR.

This warning needs better-defined behavior in C++ before it can really go in.

Rewording of the C warning (which /is/ specified by C99) coming shortly.

Jordan Rose 8cea63c5cd Change -Winternal-linkage-in-inline from ExtWarn to Warning in C++.
Per post-commit review, it's not appropriate to use ExtWarn in C++, because
we can't prove that the inline function will actually be defined in more than
one place (and thus we can't prove that this violates the ODR).

This removes the warning entirely from uses in the main source file in C++.

Jordan Rose 28cd12f265 Support -Winternal-linkage-in-inline in C++ code.
This includes treating anonymous namespaces like internal linkage, and allowing
const variables to be used even if internal. The whole thing's been broken out
into a separate function to avoid nested ifs.

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).

Eli Friedman 574c745370 Diagnose uses of function specifiers on declarations which don't declare
functions.  Fixes PR3941.
