"This patch fixes message sends to super in categories for the GNU runtime.  This used to work, but I broke it when I modified the code to emit the same thing as GCC for message sends to super in classes."

of the underlying _N builtin, not the the type of the pointee of the
actual type.  This ensures that atomics involving pointers end up
using the correct integer type when they are resolved, avoiding
aborts in codegen.

disambiguation.  There are probably a bunch of details to finish up
but this seems like a large monotonic step forward :)

"This patch is a first pass at adding support for exceptions for the GNU runtime.  There are a few limitations at present:

- @synchronized() is not yet supported at all.  gcc currently emits calls to runtime library functions that don't exist for this directive.

- Only id @catch statements are currently working.  This is enough for NS_DURING and friends, but I need to spend more time reading the output from gcc -S to work out how it finds the class pointer to make arbitrary class type catch statements work.

- I've tested it with a few common cases[1] and the clang test suite (which doesn't test exceptions for the GNU runtime, but shows I haven't broken anything else), but there are probably a lot of cases I've missed."
