Jonas Hahnfeld 7411d61c03 [Sema] Add tests for weak functions
I found these checks to be missing, just add some simple cases.

Aaron Ballman adf66b6174 Determine the attribute subject for diagnostics based on declarative information in DeclNodes.td. This greatly reduces the number of enumerated values used for more complex diagnostics; these are now only required when the "attribute only applies to" diagnostic needs to be generated manually as part of semantic processing.
This also clarifies some terminology used by the diagnostic (methods -> Objective-C methods, fields -> non-static data members, etc).

Many of the tests needed to be updated in multiple places for the diagnostic wording tweaks. The first instance of the diagnostic for that attribute is fully specified and subsequent instances cut off the complete list (to make it easier if additional subjects are added in the future for the attribute).

Rafael Espindola f1d2f0ea21 Check for internal weak decls after merging.
This fixes pr14946. The problem was that the linkage computation was done too
early, so things like "extern int a;" would be given external linkage, even if
a previous declaration was static.

John McCall 7a198cef04 When checking the 'weak' and 'weakref' attributes, look for non-external
linkage rather than the presence of the 'static' storage class specifier.
Fixes rdar://problem/8814626.

John McCall 4bb483629f Change the wording of the bad-decl-for-attribute warning and error
to make it clear that we're talking about the declarations and not the types.

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).

Tests and drivers updated, still need to shuffle dirs.
