Introduce a new interface class GRSubEngine as the subengine of GRCoreEngine.
GRExprEngine subclasses GRSubEngine now.

transform, then use the result for template instantiation. The generic
transformation fixes a few issues:

  - It copes better with template template parameters and member
  templates (when they're implemented). 
  - The logic used to replace template template parameters with their
  arguments is now centralized in TransformDecl, so that it will apply
  for other declaration-instantiation steps.
  - The error-recovery strategy is normalized now, so that any error
  results in a NULL TemplateName.

RegionStore already lazily abstracted the contents of arrays and structs, when
doing an assignment from one array/struct to another we did an explicit
element-wise copy, which resulted in a loss of laziness and huge performance
problem when analyzing many code bases.

Now RegionStoreManager handles such assignments using a new SVal could
'LazyCompoundSVal', which basically means the value of a given struct or array
(a MemRegion*) in a specific state (GRState). When we do a load from a field
whose encompassing struct binds to a LazyCompoundSVal, we essentially do a field
lookup in the original structure. This means we have essentially zero copying of
data for structs/arrays and everything stays lazy.
