for binding.
Also fixes PR 13445: "hasSourceExpression only works for implicit casts".

Users may define it to override the default ASan options.
This function has to be marked with __attribute__((no_address_safety_analysis)), because it is called before ASan is fully initialized.
Add an output test checking the __asan_default_options functionality.

of an array element (rather than at the beginning of the element) and extended
into the next element, then the load from the second element was being handled
wrong due to incorrect updating of the notion of which byte to load next. This
fixes PR13442. Thanks to Chris Smowton for reporting the problem, analyzing it
and providing a fix.

Rather than adding a ContainsUnexpandedParameterPack bit to essentially every
AST node, we tunnel the bit directly up to the surrounding lambda expression
when we reach a context where an unexpanded pack can not normally appear.
Thus any statement or declaration within a lambda can now potentially contain
an unexpanded parameter pack.

The long branch pass (fixed in r160601) no longer uses the global base register
to compute addresses of branch destinations, so it is not necessary to reserve
a slot on the stack.

This tests for the ability to include a "message" field in availability
attributes, like so:
extern void ATSFontGetName(const char *oName)
__attribute__((availability(macosx,introduced=8.0,deprecated=9.0,
message="use CTFontCopyFullName")));
This was actually supported in Clang 3.1, but we got a request for a
__has_feature so that header files can use this more safely. It's
unfortunate that the 3.1 release doesn't include this, however.

struct s {
double x1;
float x2;
};
__attribute__((regparm(3))) struct s f(int a, int b, int c);
void g(void) {
f(41, 42, 43);
}
We need to be able to represent passing the address of s to f (sret) in a
register (inreg). Turns out that all that is needed is to not mark them as
mutually incompatible.

if Condition Is Met instuctions that was not correctly determining the target
instruction.
So for a jne rel32 instruction:
% cat x.s
.byte 0x0f, 0x85, 0x09, 0x00, 0x00, 0x00
% as x.s
it was incorrectly deterining the target:
% otool -q -tv a.out
a.out:
(__TEXT,__text) section
0000000000000000 jne 0xd
and with the fix it gets this correct as:
% otool -q -tv a.out
a.out:
(__TEXT,__text) section
0000000000000000 jne 0xf

This fixes PR13438.

A warning was added in r150128 for returning non-C compatible
user-defined types from functions with C linkage.
This makes the text more clear for the case when the type isn't
decidedly non-C compatible, but incomplete.
