Disable type merging with gc attributes.  This has a number of nasty
properties at the moment:

1. It allows stuff like "__strong id x; __weak id x;".

2. For constructs like "__strong id x; id x;", subsequent references to
x lose the objc_gc attribute.

3. This incorrectly allows merges involving the address_space attribute.

4. Constructs like "id x; /* some code using x */ __weak id x;" don't
apply the objc_gc attribute consistently to all uses of x.

The first three can probably be fixed relatively easily; the fourth
would be extremely difficult to fix.

Downgrade an error about "return in a no-return function" from being
an error to being a warning that defaults to error.  If you want this to
be a warning, you have to explicitly pass -Winvalid-noreturn to clang to
map it back to a warning.

Fix for PR4285: allow intializing a const wchar_t array with a wide
string.

Initial infrastructure for class template partial specialization. Here
we have the basics of declaring and storing class template partial
specializations, matching class template partial specializations at
instantiation time via (limited) template argument deduction, and
using the class template partial specialization's pattern for
instantiation.

This patch is enough to make a simple is_pointer type trait work, but
not much else.
