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.

'objc_ownership_cfretain' -> 'cf_ownership_retain'
'objc_ownership_cfrelease' -> 'cf_ownership_release'
Motivation: Core Foundation objects can be used in isolation from Objective-C,
and this forces users to reason about the separate semantics of CF objects. More
Sema support pending.

return type and the selector. This is inconsistent with C functions
(where such attributes would be placed on the return type, not the the
FunctionDecl), and is inconsistent with what people are use to seeing.

only capture their arguments by returning them or
throwing an exception or not based on the argument
value. Patch essentially by Frits van Bommel.

The attached diff fixes the //FIXME in message send to super. This
should now be faster, and works in the presence of class posing. This
is now the same approach as used in GCC (the earlier code was a quick
hack to get something working).

'ElementRegion' on top of the VarRegion for 'x'. This causes the test
case xfail_wine_crash.c to now pass for BasicStoreManager. It doesn't
crash for RegionStoreManager either, but reports a bogus unintialized
value warning.

1) First of all, we treat _ as part of an identifier and not as
punctuation (oops).
2) Second of all, always make sure that the token that the ^ is
pointing at is fully within the "interesting" part of the range.

ElementRegion. I also removed 'ElementRegion::getArrayRegion',
although we may need to add this back.
This breaks a few test cases with RegionStore:
- 'array-struct.c' triggers an infinite recursion in RegionStoreManager. Need to investigate.
- misc-ps.m triggers a failure with RegionStoreManager as we now get the diagnostic:
'Line 159: Uninitialized or undefined return value returned to caller.'
There were a bunch of places that needed to be edit
RegionStoreManager, and we may not be passing all the correct 'element
types' down from GRExprEngine.
Zhongxing: When you get a chance, could you review this? I could have
easily screwed up something basic in RegionStoreManager.

in C++, taking into account conversions to the "composite pointer
type" so that we can compare, e.g., a pointer to a derived class to a
pointer to a base class.
Also, upgrade the "comparing distinct pointer types" from a warning to
an error for C++, since this is clearly an error. Turns out that we
hadn't gone through and audited this code for C++, ever.
Fixes <rdar://problem/6816420>.
