Pointer width on targets like PIC16 is 16-bit, while the valid index size to GEP is only 32 or 64. So promote index to 32 in such cases.

"The attached patch generates warnings of cases where an ObjC message is sent to
a nil object and the size of return type of that message is larger than the size
of void pointer. This may result in undefined return values as described in PR
2718.  The patch also includes test cases."

 - Add -pic-level clang-cc option to specify the value for the define,
   updated driver to pass this.

 - Added __pic__

 - Added OBJC_ZEROCOST_EXCEPTIONS define while I was here (to match gcc).

Tweak Sema::ActOnInstanceMessage() to look for a class method when dealing with qualified id's. This change is motivated by our desire to not support the "Class<foo>" idiom. Note that the change makes perfect sense (since all ObjC classes are also id/instances).

This allow us to document a simple migration path...change "Class <foo>" to "id <foo>".

This effects:

- <rdar://problem/6761864> Protocol qualified Class is unsupported
