Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.
Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.

Preserve the original triple in the NetBSD toolchain when using -m32 or
-m64 and the resulting effective target is different from the triple it
started with. This allows -m32 to use the same assembler/linking in
cross-compiling mode and avoids confusion about passing down target
specific flags in that case like --32.

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.

*) Try to detect as much as possible from the system itself, not the distro.
This should make it easier to port to a new distro and more likely to
work on a unknown one.
*) The distro enum now doesn't include the arch. Just use the existing
host detection support in LLVM.
*) Correctly handle --sysroot.
A small regression is that now clang will pass bitcode file to the linker.
This is necessary for the gold plugin support to work.
It might be better to detect this at configure/cmake time, but doing it in
c++ first is a lot easier.

distros listed by running
gcc main.o -o main
g++ main.o -o main
gcc main.o -o main -static
g++ main.o -o main -static
gcc f.o -o f.so -shared
g++ f.o -o f.so -shared
and comparing the ld line with the one created by clang. I also added
-m32/m64 in distros that support it.
While I tested many distros, there will always be more. If you are hit by this
it should be somewhat easy to add your distro. If you are in a hurry, do
revert this, but please inform how to detect you distro and the ld command
lines produced by the above gcc invocations. Most distros have some patches
on gcc :-(

the GCC dir. Unfortunately, this breaks -lstdc++ on SnowLeopard, etc. because
the libstdc++ dylib was hiding there. Workaround this by providing the path to
the right -lstdc++.6 (the only version used in recent memory) if we can't see an
obvious -lstdc++, but can find = -lstdc++.6.

ToolChain. This fixes a potenial bad cast when running Clang on PPC code, since
the tool chain in effect is not a subclass of the Darwin one, but we were
treating it like it was.
- This introduces some gross code duplication, but the right fix for it is to
just move the Driver to start depending on the targets in libBasic, so I am
not planning on fixing it immediately.

- Replace -cc1 level -fobjc-legacy-dispatch with -fobjc-dispatch-method={legacy,non-legacy,mixed}.
- Lift "mixed" vs "non-mixed" policy choice up to driver level, instead of being buried in CGObjCMac.cpp.
- No intended functionality change.
