432f10df68 The default CPU on FreeBSD for i386 should be i486, not pentium4.

ee8188a23b For linking on FreeBSD, don't add a hardcoded "-L/usr/lib", but 
retrieve the library paths from the ToolChain object instead.

Copy the relevant code from linuxtools::Link::ConstructJob(), and
replace the std::string stuff with llvm::StringRef, while we're here.

22f60303f2 Don't warn about "clang -use-gold-plugin -c ...". With this users can say 
CC="clang -use-gold-plugin" CFLAGS=-emit-llvm ../configure...

da20991a1b Make -fobjc-nonfragile-abi and -fgnu-runtime imply -fblocks (unless -fno-blocks is specified), because this combination of flags defines an Objective-C runtime that includes a blocks runtime.

74f8711802 Fix a tiny goof in the Driver's logic which caused the explicit presence 
of -fexceptions to disably C++ exceptions. The correct code was in the
ObjC branch, this just mirrors that logic on the C++ side of things.
Thanks to John Wiegley for pointing this out.

e96ab55b28 Add a -fcxx-exceptions flag to the frontend, which can be used to enable 
C++ exceptions, even when exceptions have been turned off using -fno-exceptions.
Make the -fobjc-exceptions flag do the same thing, but for Objective-C exceptions.

C++ and Objective-C exceptions can also be disabled using -fno-cxx-excptions and
-fno-objc-exceptions.

31ea2f14bc Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 instead.

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"

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.
