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).

clang.
 - We will eventually want some more driver infrastructre for this
   probably.

 - For now, the clang-cc interface stays relatively the same, but we
   don't accept multiple instances anymore, or the [no-] variants
   directly.

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/6761939> TASK: File source change radars for "qualified Class" errors
- <rdar://problem/6761864> Protocol qualified Class is unsupported

exception with this attribute we don't need to emit a weak definition

 - Changed method names to match gcc (categories names still aren't
   mangled in).

 - Expose correct name for class and metadata symbols (although
   -fvisibility=hidden isn't yet correct).

 - Remove several things from llvm.used that didn't need to be there
   (I suspect this can still be trimmed).

 - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
   needed).

 - Hide EH type class info with -fvisibility=hidden

 - Change setGlobal[Option]Visibility to not change the visibility of
   functions with internal linkage.

are considered 'live'. This hack isn't needed anymore because we have a
separation in the path-sensitive analyzer between variable names and bindings;
the analyzer can continue to reason about the storage of a variable after its
name is no longer directly referenced.  Now the live variables analysis literally means "is this name live".

Along this line, update the dead stores checker to explicitly look for variables
whose values have escaped.

__OBJC_GC__ is also darwin specific, but seems reasonable to always
define it when in objc-gc mode.

This fixes rdar://6761450
