Fixup debug information for the location information for __block

A typical utterance would be:

%0 = load i8** %forwarding ; <i8*> [#uses=1]
%1 = bitcast i8* %0 to %0* ; <%0*> [#uses=1]
%x = getelementptr %0* %1, i32 0, i32 4 ; <i32*> [#uses=1]
%2 = bitcast i32* %x to { }* ; <{ }*> [#uses=1]
call void @llvm.dbg.declare({ }* %2, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable to { }*))

initial support for ObjC exceptions with the GNU runtime:

"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."

"Fix" a problem with debug info in the presence of always_inline
...
function calls. For a program like this:
#include <stdio.h>
static __inline__ __attribute__((always_inline))
int bar(int x) { return 4; }
int main() {
int X = bar(4);
printf("%d\n", X);
}
clang was not outputing any debug info for the body of main(). This is
because the backend is getting confused by the region_start/end that clang
is emitting for block scopes. For now, just disable these (matching llvm-gcc),
this stuff is in progress of rework anyway.

Don't allow clients to traverse into superclass synthesized properties
...
via CollectObjCIvars.
- In places where we need them, we should have the implementation and
access the properties through it.
This is a fairly substantial functionality change:
1. @encode no longer encodes synthesized ivars, ever.
2. The ivar layout bitmap no longer encodes information for
synthesized ivars in superclasses. Well, actually I had already
broken that, but it is intentional now.
We are now differing substantially from llvm-gcc and gcc
here. However, in my opinion this fundamentally *must* work if
non-fragile classes are to work. Without this change, the result of
@encode and the ivar layout depend on the order that the
implementation is seen in a file (if it is in the same file with its
superclass). Since both scenarios should work the same, our behavior
is now consistent with gcc behavior as if an implementation is never
seen following an implementation of its superclass.
Note that #2 is only a functionality change when (A) an
implementation appears in the same translation unit with the
implementation of its superclass, and (B) the superclass has
synthesized ivars. My belief is that this situation does not occur in
practice.
I am not yet sure of the role/semantics of @encode when synthesized
ivars are present... it's use is fairly unsound in a non-fragile world.
