TemplateTypeParmType with the substituted type directly;  instead, replace it
with a SubstTemplateTypeParmType which will note that the type was originally
written as a template type parameter.  This makes it reasonable to preserve
source information even through template substitution.

Also define the new SubstTemplateTypeParmType class, obviously.

For consistency with current behavior, we stringize these types as if they
were the underlying type.  I'm not sure this is the right thing to do.
At any rate, I paled at adding yet another clause to the don't-desugar 'if'
statement, so I extracted a function to do it.  The new function also does
The Right Thing more often, I think:  e.g. if we have a chain of typedefs
leading to a vector type, we will now desugar all but the last one.

TypeLoc class names to be $(Type classname)Loc.  Rewrite the visitor.
Provide skeleton implementations for all the new TypeLocs.

Handle all cases in PCH.  Handle a few more cases when inserting
location information in SemaType.

It should be extremely straightforward to add new location information
to existing TypeLoc objects now.

format, so that we don't end up with multiple declaration and types
blocks. Also, fix a few obscure bugs with PCH loading and generation:

  - If the DeclIDs DenseMap reallocates while we are writing a
    declaration (due to recursively writing other declarations), we
    could end up writing a bad ID to ExternalDefinitions.
  - When loading an ArrayLoc (part of DeclaratorInfo), we need to set
    the size expression to NULL if no size expression was provided.

PCH -> AST rewriting is still partly broken, unfortunately.

this information to help CIndex filter out declarations that came from
a precompiled header (rather than from an AST file). Further down the
road, it can be used to help implement multi-level precompiled
headers.

only supporting a single stat cache. The immediate benefit of this
change is that we can now generate a PCH/AST file when including
another PCH file; in the future, the chain of stat caches will likely
be useful with multiple levels of PCH files.

most of the unsafe boilerplate out of TypeLoc.  Create a QualifiedLoc class
to represent the idea that we *might* start representing source locations
of qualifiers.  Dealing with qualifiers explicitly like this also lets us
efficiently ignore them in all the concrete cases.

This should make it obvious and easy to add new TypeLoc subclasses.
