to a class template. For example, the template-id 'vector<int>' now
has a nice, sugary type in the type system. What we can do now:

  - Parse template-ids like 'vector<int>' (where 'vector' names a
    class template) and form proper types for them in the type system.
  - Parse icky template-ids like 'A<5>' and 'A<(5 > 0)>' properly,
    using (sadly) a bool in the parser to tell it whether '>' should
    be treated as an operator or not.

This is a baby-step, with major problems and limitations:
  - There are currently two ways that we handle template arguments
  (whether they are types or expressions). These will be merged, and,
  most likely, TemplateArg will disappear.
  - We don't have any notion of the declaration of class template
  specializations or of template instantiations, so all template-ids
  are fancy names for 'int' :)

Add a simplified EmitJumpThroughFinally and use it in CGObjC in preparation of making it use the cleanup stack.

If people could beat on it and let me know if there are any new
semantics required by newer language standards or DRs or any little
details I goofed on, I'd be happy to fix any issues found.

Add support for emitting cleanup blocks. Make EmitCompoundStatement emit cleanup blocks if necessary

Add a simple RAII object, to be used for pushing a cleanup entry and make the insertion point be the cleanup block.

correctly.  This should lay the ground work to throw the big switch
and start code gening break and continue in the presense of vlas.

This will allow us to generate break and continue even if vlas are
involved without worry that we'll silently generate bad code.

 - Currently, this is producing poor code, but we prefer correctness
   to performance for now. Eventually we should be able to generally
   avoid having to set the alignment when we control the alignment of
   the alloca.

 - This knocks out 33/1000 failures on my single argument ABI tests,
   down to 22/1000 and 18 of these appear to be gcc bugs. Woot.

 - No intended functionality change, this is essentially enabling
   direct passing of complex and aggregate values, which no ABI is
   using.
