 - This is not very precise, we use it to drive the "forward-to-gcc"
   predicate, when trying to talk to a generic gcc tool.

 - Slightly better than what ccc was doing, and should be good
   enough. Platforms which want a robust driver should implement a
   proper tool chain.

Driver: Make sure to get the default arch name from the tool chain, not the
host; the toolchain may differ based on command line arguments.

Driver: Pass HostInfo reference into ToolChain.

Refactor instantiation of declarations within a template into a much
cleaner visitor framework.

Added a visitor for declarations, which is quite similar to the
visitor for statatements.

Driver: Pass Driver reference down into Host info, which will need it
to pass to ToolChains, which may need Driver specific information (for
example, to form search paths).

Driver: Fix typo ArgList destructor.

retain/release checker: Add support for reasoning about -dealloc.

Implement instantiation of enums within class templates. This isn't
quite as great as it sounds, because, while we can refer to the
enumerator values outside the template, e.g.,

  adder<long, 3, 4>::value

we can't yet refer to them with dependent names, so no Fibonacci
(yet).

InstantiateClassTemplateSpecialization is getting messy; next commit
will put it into a less-ugly state.

Driver: Hide HostInfo implementations.
 - Also, normalize arch names a tad and stub out getToolChain
   implementations.

Driver: Add two option form of ArgList::getLastArg.

Driver: Add logic for computing where to put job outputs (pipe,
temporary file, user provided name, derived name).

Driver: Add list of temporary and result files to Compilation.

Add ArgList::MakeArgString and make ArgList::Make* const.
 - Slightly strange, but the idea is that the ArgList data structure
   is primarily a list of arguments; we want to allow clients to still
   add argument strings to an ArgList to avoid worrying about string
   lifetimes (or unnecessary string copying).

Fix a problem noticed by Anders, where we were creating
IntegerLiterals during instantiation when we should be creating either
a boolean literal (CXXBoolLiteralExpr) or a character literal
(CharacterLiteral).
