Reinstate r185229, reverted in r185256, with a tweak: further ignore the
standard's rule that an extern "C" declaration conflicts with any entity in the
global scope with the same name. Now we only care if the global scope entity is
a variable declaration (and so might have the same mangled name as the extern
"C" declaration). This has been reported as a standard defect.
Original commit message:
PR7927, PR16247: Reimplement handling of matching extern "C" declarations
across scopes.
When we declare an extern "C" name that is not a redeclaration of an entity in
the same scope, check whether it redeclares some extern "C" entity from another
scope, and if not, check whether it conflicts with a (non-extern-"C") entity in
the translation unit.
When we declare a name in the translation unit that is not a redeclaration,
check whether it conflicts with any extern "C" entities (possibly from other
scopes).

Fix PR16060.
The testcase in PR16060 points out that while template arguments can
show that a type is not externally visible, the standards still says
they have external linkage.
In terms of our implementation, it means that we should merge just the
isExternallyVisible bit, not the formal linkage.

Fix linkage computation for derived types in inline functions.
John noticed that the fix for pr15930 (r181981) didn't handle indirect
uses of local types. For example, a pointer to local struct, or a
function that returns it.
One way to implement this would be to recursively look for local
types. This would look a lot like the linkage computation itself for
types.
To avoid code duplication and utilize the existing linkage cache, this
patch just makes the computation of "type with no linkage but
externally visible because it is from an inline function" part of the
linkage computation itself.

Put friend decls in the correct context.
When we find a friend declaration we have to skip transparent contexts for doing
lookups, but we should not skip them when inserting the new decl if the lookup
found nothing.

better a better error message for
const int a = 5;
static const int a;

Use isExternalLinkage instead of hasExternalLinkage.
Having these not be the same makes an easy to misuse API. We should audit the
uses and probably rename to something like
foo->hasExternalLinkage():
The c++ standard one. That is UniqueExternalLinkage or ExternalLinkage.
foo->hasUniqueExternalLinkage():
Is UniqueExternalLinkage.
foo->hasCogeGenExternalLinkage():
Is ExternalLinkage.

Fix linkage related crash.
This test was exactly the opposite of what it should be. We should check if
there old decl has linkage (where it makes sense) and if the new decl has
the extern keyword.

Fix 41 of the 61 tests which fail with modules enabled: we were computing and
caching the linkage for a declaration before we set up its redeclaration chain,
when determining whether a declaration could be a redeclaration of something
from an unimported submodule. We actually want to look at the declaration as if
it were not a redeclaration here, so compute the linkage but don't cache it.

Remove the hack that avoided mangling static functions in extern C contexts.
Weather we should give C language linkage to functions and variables with
internal linkage probably depends on how much code assumes it. The standard
says they should have no language linkage, but gcc and msvc assign them
C language linkage.
This commit removes the hack that was preventing the mangling on static
functions declare in extern C contexts. It is an experiment to see if we
can implement the rules in the standard.
If it turns out that many users depend on these functions and variables
having C language linkage, we should change isExternC instead and try
to convince the CWG to change the standard.

merge hasCLanguageLinkage and isExternC. Keep the shorter name.
I added hasCLanguageLinkage while fixing some language linkage bugs some
time ago so that I wouldn't have to check all users of isExternC. It turned
out to be a much longer detour than expected, but this patch finally
merges the two again. The isExternC function now implements just the
standard notion of having C language linkage.

Add a getLanguageLinkage method to VarDecls and FunctionDecls. Use it to fix
some cases where functions with no language linkage were being treated as having
C language linkage. In particular, don't warn in
extern "C" {
static NonPod foo();
}
Since getLanguageLinkage checks the language linkage, the linkage computation
cannot use the language linkage. Break the loop by checking just the context
in the linkage computation.
