All includes from .cc to .h are preserved, even when transitively included.
It's clear that there are far too many includes in header files, and we should be more aggressive with forward declarations. tint:532 will continue to track this work.
There are, however, plenty of includes that have accumulated over time which are no longer required directly or transitively, so this change starts with a clean slate of *required* includes.

Appends an error message with the tint compiler source location to the
provided diagnositic list, and then calls the global error handler if
one is set.
Tests and the sample app now register an error handler to print the
diagnostic list to stderr and abort when NDEBUG is not defined.
All uses of assert(false) have been fixed up to use these macros.

The CloneContext was previously dealing with pointers to CastableBase, which has no guarantees that the object was actually cloneable.
Add a Cloneable base class that CloneContext can use instead.
Improves readability and produces cleaner compiler errors if you try to clone a non-cloneable object.

And assert that the cast succeeded.
There is a danger with Replace() or ReplaceAll(), where you can end up replacing a node with another node of an incompatible type for some reference of that object. Previously this would silently cast to the incorrect type, and Bad Things would happen. Now we will assert in this situation.
I have not observed this issue happening (all current uses of Replace() and ReplaceAll() are believed to be safe). This is just an edge case I've spotted and wanted to add some safety belts for.

Program is now immutable*, and remains part of the public Tint

ProgramBuilder is the mutable builder for Programs, and is not part of
the public Tint interface. ast::Builder has been folded into
ProgramBuilder.
Immutable Programs can be cloned into a mutable ProgramBuilder with
Program::CloneAsBuilder().
Mutable ProgramBuilders can be moved into immutable Programs.

Enforce all places where Dawn passes in or returns a ast::Module, now takes a `const Program* ` or returns a `Program`.
As the end goal of all this is to have immutable Programs, all Program inputs take a pointer instead of moving the actual object.
As consumers of a Program are now all const, we have to const_cast to work around all the places we've been incorrectly mutating a ast::Module.
These const_casts are temporary, and will be fixed in the next set of changes.
