The AuroraUX toolchain has conflicting wchar_t between the system stdlib.h header and the clang stddef.h header where clang was defining as int where we use long.

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.

 - I have this crazy dream that one day someone will invent a miraculous tool so
   that developers, instead of hand optimizing their source code to obscure its
   intent and decrease its maleability, will instead write what they mean, and
   this strange and wonderful tool -- which I imagine would be called something
   fancy sounding like "an optimizing compiler" -- will make their code fast
   *for* them. With all the saved time, developers could maybe even focus on
   making the magic "optimizing compiler" better!!

 - No intended functionality change, all though I expect the universe to mock me
   for snarkiness.

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.

When resolving the address of an overloaded function or function template, mark the result as referenced.

The most important effect of this is that function templates only referenced by address expressions now get instantiated. This, in turn, means that Hello World compiles with the Apache stdcxx library even when using endl.

llvm-svn: 84363

Taking the address of an overloaded function with an explicit address-of operator wrapped the operator in an implicit cast that added yet another pointer level, leaving us with a corrupted AST, which crashed CodeGen in the test case I've added. Fix this by making FixOverloadedFunctionReference return whether there was an address-of operator and not adding the implicit cast in that case.

In some dependent contexts, incomplete array types persist into FinalizeDeclaratorGroup. Don't require them to have a complete type. This allows us to compile Hello World with the Apache stdcxx library. If you don't use endl, it even links and runs.
