. move compiler-rt to a separate directory so the -L argument only includes compiler-rt (thanks joerg)
. build all clang subdirs
. switches the Minix platform to ELF
. normalizes toolchain invocation

version of Ubuntu. It has a very broken multiarch configuration, and so
we need special logic to handle it correctly. Fixing and testing this
uncovered a few other trivial issues with the logic that are fixed as
well.
I added tests to cover this as it is hard to notice if you install
recent versions of the OS.

toolchain. The logic is mostly generic already, and where possible
should be made more generic. Also, it has no impact other than to expose
a set of methods which each toolchain can then query to setup their
desired configuration. These should be available to toolchains beyond
just Linux.

the detected GCC installation. This allows us to expose another aspect
of what we detected: the GCC version. This will be used shortly.

variable to begin with... As I'm planning to add include root
information to this object, this would have caused confusion. It didn't
even *actually* hold the include root by the time we were done with it.

toolchain instead of merely using it in the constructor. This will allow
us to query it when building include paths as well as the file search
paths built in the constructor. I've lifted as little of it as I could
into the header file.
Eventually this will likely sink down into some of the Generic
toolchains and be used on more platforms, but I'm starting on Linux so
I can work out all the APIs needed there, where it is easiest to test
and we have the most pressing need.

the first (and diff-noisiest) step to making Linux header searching
tremendously more principled and less brittle. Note that this step
should have essentially no functional impact. We still search the exact
same set of paths in the exact same order. The only change here is where
the code implementing such a search lives.
This has one obvious negative impact -- we now pass a ludicrous number
of flags to the CC1 layer. That should go away as I re-base this logic
on the logic to detect a GCC installation. I want to do this in two
phases so the bots can tell me if this step alone breaks something, and
so that the diffs of the refactoring make more sense.

Windows. There are still FIXMEs and lots of problems with this code.
Some of them will be addressed shortly by my follow-up patches, but most
are going to wait until we isolate this code and can fix it properly.
This version should be no worse than what we had before.

Check whether the libc++ library is available when using -stdlib=libc++,
and also adjust the check for whether to link with -lgcc_s.1.

This replaces the hack to read UNAME_RELEASE from the environment when
identifying the OS version on Darwin, and it's more flexible. It's also
horribly ugly, but at least this consolidates the ugliness to touch less of
the code so that it will be easier to rip out later.

feature akin to the ARC runtime checks. Removes a terrible hack where
IR gen needed to find the declarations of those symbols in the translation
unit.

structure to hold inferred information, then propagate each invididual
bit down to -cc1. Separate the bits of "supports weak" and "has a native
ARC runtime"; make the latter a CodeGenOption.
The tool chain is still driving this decision, because it's the place that
has the required deployment target information on Darwin, but at least it's
better-factored now.

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.

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.
