gets placed inside a main function, and should not itself be a main
function. This is silently hidden in GCC-hosted builds because the
inner main looks like a nested function declaration, which GCC supports.
In builds with compilers which do not support nested functions (by default),
this was causing an error, which caused these autoconf checks to fail,
leaving their options disabled.
This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu
llvm-gcc selfhost builds, among other things.
This also includes a regenerated configure, as the diff is small and telling.

in r86005 and unintentionally changed the default from -O3 to -O2.
- It's odd the things automated perf testing turns up! :)
- Also, the configure diff is messed up slightly. It looks like someone either
didn't regenerate configure correctly (or I didn't), or autoconf has some
funnyness in it. Eric, any ideas?
This has been at -O2 for so long, that I am slightly nervous that this change
will uncover miscompiles of LLVM on other systems. If that is the case, I think
we should just set the default universally at -O3, and let developers/vendors
use -O3 if they want it and have tested it.

now configures prerequisite projects individually but also ignores them in the
big project switch statement to avoid the incorrect warning.

projects rely upon llvm-gcc, the LLVM test suite, and poolalloc. This ensures
that the aforementioned projects have their object trees created first so that
other projects can find their object trees when they themselves are configured.

The MicroBlaze is a highly configurable 32-bit soft-microprocessor for
use on Xilinx FPGAs. For more information see:
http://www.xilinx.com/tools/microblaze.htmhttp://en.wikipedia.org/wiki/MicroBlaze
The current LLVM MicroBlaze backend generates assembly which can be
compiled using the an appropriate binutils assembler.

Comes in two parts:
1. Use --with-clang=path/to/clang/compiler to select an installed clang, or
--with-built-clang to have the makefiles use the clang which will be built
as the LLVM capable compiler. If neither is given, --with-built-clang will
be used if the Clang sources are checked out into the standard location
(tools/clang).
2. Use --with-llvmcc={llvm-gcc,clang,none} to specify which LLVM capable
compiler to use. If not given, then llvm-gcc will be used if available,
otherwise Clang.
Makefile support still to come.
Eric, Doug, Chris, seem reasonable?

--enable-shared configure flag to have the tools linked shared. (2.7svn is just
$(LLVMVersion) so it'll change to "2.7" in the release.) Always link the
example programs shared to test that the shared library keeps working.
On my mac laptop, Debug libLLVM2.7svn.dylib is 39MB, and opt (for example) is
16M static vs 440K shared.
Two things are less than ideal here:
1) The library doesn't include any version information. Since we expect to break
the ABI with every release, this shouldn't be much of a problem. If we do
release a compatible 2.7.1, we may be able to hack its library to work with
binaries compiled against 2.7.0, or we can just ask them to recompile. I'm
hoping to get a real packaging expert to look at this for the 2.8 release.
2) llvm-config doesn't yet have an option to print link options for the shared
library. I'll add this as a subsequent patch.

same effect that "host-only" used to have, but can be combined with other
targets. host-only is still available as a synonym but no longer documented.

Despite common miscomceptions, iterator.h is alive and well. It broke the build
bots for several hours. And yet no one bothered to look at them.
Gabor and Doug, please review your changes and make sure that they actually
build before resubmitting them.
