This patch attempts to fix the merging of __strong/__weak attributes
in merge_types. It is incomplete. We probably want to issue
a warning if user attempts to change the attribute from __weak to
__strong or vice-vera. It also assumes that a __weak/__strong
attribute can not be specified with other (currently one) type
attriute.

PR4287: allow a variadic prototype to make a subsequent K&R style

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.
