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.
