Provide a mode for ImmutableMap/ImmutableSet to not automatically canonicalize the internal functional AVL trees.  This should speedup clients that use ImmutableMap/ImmutableSet but don't require fast comparisons of maps.

GlobalValue is destroyed.  Function destruction still leaks machine code and
can crash on leaked stubs, but this is some progress.

"there is not any instruction with attached debug info in this module" does not mean "there is no debug info in this module". :)

Copy metadata when value is RAUW'd. It is debatable whether this is the right approach for custom metadata data in general. However, right now the only custom data user, "dbg", expects this behavior while FE is constructing llvm IR with debug info.

-funit-at-a-time is the default however some current makefiles pass -fno-unit-at-a-time which is ignored by GCC, we should warn about this not error out.

template as a specialization. For example, this occurs with:

  template<typename T>
  struct X {
    template<typename U> struct Inner { /* ... */ };
  };

  template<> template<typename T>
  struct X<int>::Inner {
    T member;
  };

We need to treat templates that are member specializations as special
in two contexts:

  - When looking for a definition of a member template, we look
    through the instantiation chain until we hit the primary template
    *or a member specialization*. This allows us to distinguish
    between the primary "Inner" definition and the X<int>::Inner
    definition, above.
  - When computing all of the levels of template arguments needed to
    instantiate a member template, don't add template arguments
    from contexts outside of the instantiation of a member
    specialization, since the user has already manually substituted
    those arguments.

Fix up the existing test for p18, which was actually wrong (but we
didn't diagnose it because of our poor handling of member
specializations of templates), and add a new test for member
specializations of templates.

function templates.

This commit ensures that friend function templates are constructed as
FunctionTemplateDecls rather than partial FunctionDecls (as they
previously were). It then implements template instantiation for friend
function templates, injecting the friend function template only when
no previous declaration exists at the time of instantiation. 

Oh, and make sure that explicit specialization declarations are not
friends.
