ce8dd3a5d4 Add a new ObjCExceptions member variable to LangOptions. This controls whether Objective-C exceptions are enabled or not (they are by default).

1094bb101b Driver/Darwin: Support -Wl, with -Xarch_. This doesn't work naturally because of 
the special way we model "linker input" arguments.

31ea2f14bc Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 instead. 
No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32.

a6d04d541d [analyzer] Use the new registration mechanism on some of the internal checks. These are: 
StackAddrLeakChecker
ObjCAtSyncChecker
UnixAPIChecker
MacOSXAPIChecker

The rest have/create implicit dependencies between checkers and need to be handled differently.

556c45e9c5 [analyzer] Overhauling of the checker registration mechanism. 
-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
	Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
	-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
 register them with the CheckerManager which will be the entry point for all checker-related functionality.

Currently only the self-initialization checker takes advantage of the new mechanism.

906bb9047a improve compatibility with GCC: when generating the ".d" filename to use 
and the filename has multiple .'s in it, use the last.  For example, "foo.bar.cpp"
should produce "foo.bar.d" not "foo.d".  Patch by Johan Boule in PR8391

f6ab5ff7d7 Driver: tweak handling of '--analyze' to invoke 
analyzer -cc1 options that are tailored to the
input type.  If the input type is "C++", we should
only run the dead stores checker (for now).  Similarly,
checks specific to Objective-C should only run
on Objective-C Code.

1d56c9eed7 Add -fobjc-default-synthesized-properties flag 
to allow us to explicitly control whether or
not Objective-C properties are default synthesized.
Currently this feature only works when using
the -fobjc-non-fragile-abi2 flag (so there is
no functionality change), but we can now turn
off this feature without turning off all the features
coupled with -fobjc-non-fragile-abi2.
