the front-end (as far as the preprocessor goes), follow the usual logic of
inserting the (original include path) name into the predefines buffer. This
pushes the responsibility for handling this to PCH instead of the front-end.  In
PCH this requires being a little more clever when we diff the predefines
buffers.

Neither of these solutions are particularly great, I think what we eventually
should do is something like gcc where we insert a special marker to indicate the
PCH file, but then run the preprocessor as usual. This would be clearer and
would allow us to drop the overly clever predefines handling.

 - FileCheck is a *huuuuge* improvement here.

 - Still feels like we could use a better tool for this though, either teach
   llvm-dis to spit out the FileCheck syntax, or provide another tool to turn a
   .ll into a "matchable" input.

 - Also on my Christmas list is better FileCheck diagnostics with missing
   variables or mismatches.

tons of std::string trashing. I plan to move this and other fun string munging
utilities to a StringRefExtras.h at some point if no one beats me to it.

On a synthetic benchmark on x86_64, llvm-gcc actually generates code thats 10%
faster using the StringRef version. gcc miscompiles the synthetic benchmark,
which I'm crossing my fingers and hoping won't happen here. clang compiles the
sythetic benchmark correctly (wootness), but the StringRef version is
slower. Silly clang.

the old builder API.  This percolated a bunch of changes up to the
Checker class (where CheckLocation has been renamed VisitLocation) and
GRExprEngine.  ProgramPoint now has the notion of a "LocationCheck"
point (with PreLoad and PreStore respectively), and a bunch of the old
ProgramPoints that are no longer used have been removed.

parameters. Rather than storing them as either declarations (for the
non-dependent case) or expressions (for the dependent case), we now
(always) store them as TemplateNames. 

The primary change here is to add a new kind of TemplateArgument,
which stores a TemplateName. However, making that change ripples to
every switch on a TemplateArgument's kind, also affecting
TemplateArgumentLocInfo/TemplateArgumentLoc, default template
arguments for template template parameters, type-checking of template
template arguments, etc.

This change is light on testing. It should fix several pre-existing
problems with template template parameters, such as:
  - the inability to use dependent template names as template template
  arguments
  - template template parameter default arguments cannot be
  instantiation

However, there are enough pieces missing that more implementation is
required before we can adequately test template template parameters.

handling template template parameters properly. This refactoring:

  - Parses template template arguments as id-expressions, representing
    the result of the parse as a template name (Action::TemplateTy)
    rather than as an expression (lame!).

  - Represents all parsed template arguments via a new parser-specific
    type, ParsedTemplateArgument, which stores the kind of template
    argument (type, non-type, template) along with all of the source
    information about the template argument. This replaces an ad hoc
    set of 3 vectors (one for a void*, which was either a type or an
    expression; one for a bit telling whether the first was a type or
    an expression; and one for a single source location pointing at
    the template argument).

  - Moves TemplateIdAnnotation into the new Parse/Template.h. It never
    belonged in the Basic library anyway.
