This patch makes us report one for
extern "C" {
void test6_f() {
extern int test6_b;
}
}
extern "C" {
static float test6_b;
}
Not because we think the declaration would be extern C, but because of the rule:
An entity with C language linkage shall not be declared with the same name as an entity in global scope...
We were just not looking past the extern "C" to see if the decl was in global
scope.

Without this patch we produce an error for
extern "C" {
void f() {
extern int b;
}
}
extern "C" {
extern float b;
}
but not for
extern "C" {
void f() {
extern int b;
}
}
extern "C" {
float b;
}

a view over the contents of a DeclContext without exposing the implementation
details of the StoredDeclsMap. Use this in LookupVisibleDecls to find the
visible declarations. Fixes PR12339!

For the test case added to function-redecl.cpp, we were previously complaining
about a mismatch in the parameter types, since the definition used the
typedef'd type.

- 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).

- 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"
