DebugInfo: Improvements/corrections to conservative emission of types in explicit template instantiation declarations

* detect member function explicit specializations correctly

DebugInfo: Emit only the declaration of a class template that has an explicit instantiation declaration (& always emit such a type when there's an explicit instantiation definition)

We should only have this optimization fire when the explicit
instantiation definition would cause at  least one member function to be
emitted, thus ensuring that even a compiler not performing this
optimization would still emit the full type information elsewhere.

But we should also pessimize output still by always emitting the
definition when the explicit instantiation definition appears so that at
some point in the future we can depend on that information even when no
code had to be emitted in that TU. (this shouldn't happen very often,
since people mostly use explicit spec decl/defs to reduce code size -
but perhaps one day they could use it to explicitly reduce debug info
size too)

This was worth about 2% for Clang and LLVM - so not a huge win, but a
win. It looks really great for simple STL programs (include <string> and
just declare a string - 14k -> 1.4k of .dwo)

This needs to modify a line table test to account for the new lexical
block created to hold the new discriminator value.

adaptable predicate. It has been fixed and we really don't want to
require an indirect call for every predicate evaluation.

I guess we're still using LLVM_DELETED_FUNCTION instead of = delete. This should fix a complaining built bot.

Serialized diagnostics were accidentally using the AST diagnostic level values
rather than a dedicated stable enum, so the addition of "remark" broke the
reading of existing serialized diagnostics files. I've added a .dia file
generated from Xcode 5's Clang to make sure we don't break this in the future.

Returning CXString is not appropriate if we want to switch to a non-string format buffer.

It isn't appropriate for a tool to be stomping over the dependency files,
especially if the actual build uses a compiler other than Clang or the tool
cannot find all the headers for some reason (which would cause the existing
dependency file to be deleted).

If a tool actually needs to care about dependency files we can think about
adding a mechanism for getting to this information.

This adds support for the PPC "wc" inline asm constraint (used for allocating
individual CR bits). Support for this constraint type was recently added to the
LLVM PowerPC backend. Although gcc does not currently support allocating
individual CR bits, this identifier choice has been coordinated with the gcc
PowerPC team, and will be marked as reserved for this purpose in the gcc
constraints.md file.

Prior to this change, none of the multi-character PPC constraints were handled
correctly (the '^' escape character was not being added as required by the
parsing code in LLVM). This should now be fixed. I'll add tests for these other
constraints as support is added for them in the backend.
