Implement __declspec(selectany) under -fms-extensions

selectany only applies to externally visible global variables.  It has
the effect of making the data weak_odr.

The MSDN docs suggest that unused definitions can only be dropped at
linktime, so Clang uses weak instead of linkonce.  MSVC optimizes away
references to constant selectany data, so it must assume that there is
only one definition, hence weak_odr.

[ms-cxxabi] Look up operator delete() at every virtual dtor declaration.

While the C++ standard requires that this lookup take place only at the
definition point of a virtual destructor (C++11 [class.dtor]p12), the
Microsoft ABI may require the compiler to emit a deleting destructor
for any virtual destructor declared in the TU, including ones without
a body, requiring an operator delete() lookup for every virtual
destructor declaration.  The result of the lookup should be the same
no matter which declaration is used (except in weird corner cases).

This change will cause us to reject some valid TUs in Microsoft ABI
mode, e.g.:

struct A {
  void operator delete(void *);
};

struct B {
  void operator delete(void *);
};

struct C : A, B {
  virtual ~C();
};

As Richard points out, every virtual function declared in a TU
(including this virtual destructor) is odr-used, so it must be defined
in any program which declares it, or the program is ill formed, no
diagnostic required.  Because we know that any definition of this
destructor will cause the lookup to fail, the compiler can choose to
issue a diagnostic here.

PR14606: Debug Info for namespace aliases/DW_TAG_imported_module

This resolves the last of the PR14606 failures in the GDB 7.5 test
suite. (but there are still unresolved issues in the imported_decl case
- we need to implement optional/lazy decls for functions & variables
like we already do for types)

In -ast-dump, only dump comments when dumping the actual Decl to which they
attach, rather than merging all comments on the declaration chain. This gives a
more faithful dump, and has the side benefit of unbreaking uses of dump() from
within AST deserialization (where the redeclaration chain may not be sane).
