This built clean with clang, but if we see false positives on the bots
then we'll revert and turn it into a compiler specific check.

catches uses of an extremely minor and widely-available C++ extension (which
every C++ compiler I could find supports, but EDG and Clang reject in strict
mode).
The diagnosed code pattern looks like this:
struct X {
union {
struct {
int a;
int b;
} S;
};
};

This adds a new --with-python option to allow configuration of the python binary
for building. If not specified, $PATH will be searched for common python binary
names (python, python2, python3). If specified, and the path is not executable,
it will attempt to search $PATH.

configure checks whether -Wno-missing-field-initializers is a valid
compiler flag but it was never actually used in Makefile.rules.
Enable it to avoid some ridiculous warnings from gcc.

If the compiler is gcc, disable variants of -Wuninitialized depending
on the gcc version. This gets a lot of false positive warnings out of
the build.
Generate a new configure for the gcc -Wno-uninitialized fix.
Pick up -Wno-uninitialized from configure
Add the option -Wno[-maybe]-uninitialized as determined by configure.

into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.
There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.
The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.
I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).
I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

When aliasing tools, rather than using the base TOOLEXENAME, we should
instead use the built tool's basename (for 'make') or the installed
tool's basename (for 'make install').
This should not cause any changes for anyone building unprefixed 'clang'
and 'clang++' tools.

The Apple buildbots have been modified not to pass --target,
so they shouldn't choke on a default program prefix anymore.

The Apple buildbots are set up to pass --target to configure for both
cross- and non-cross-compile builds, and the standard autoconf response
to this is to set the program prefix to '<target>-'. Until we can figure
out the proper way to handle this (don't pass --target? pass an explicit
--program-prefix=""? don't auto-populate program_prefix with target_alias?)
it's more important to keep the buildbots running.

to store additional flag options since too many things can
and do override CPPFLAGS. Also, this is exported, unlike CPPFLAGS
so it can be actually used elsewhere. This should enable us
to remove the AC_SUBSTs in the intel checks, but I have no way
of testing it.

llvm-ld is no longer useful and causes confusion and so it is being removed.
* Does not work very well on Windows because it must call a gcc like driver to
assemble and link.
* Has lots of hard coded paths which are wrong on many systems.
* Does not understand most of ld's options.
* Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} |
ld, or fully replaced by Clang.
I know of no production use of llvm-ld, and hacking use should be
replaced by Clang's driver.

- On OS X 10.7+ this is apparently recommended practice. This maybe should
become a configurey thing one day, but I'm not sure it is right to
automatically turn it on.

Clang builds. The detection logic for compilers that support the warning
isn't working. Rafael is going to investigate it, but didn't want people
to have to wade through build spam until then.

This was disabled years ago because of a bug in GCC 4.1, which is
on our "broken compilers" list for other reasons. Saving ~500k
on a clang binary (Release+Asserts) is well worth dropping support
for it.
We currently disable it for shared libraries (where it would bring
the biggest win) because clang is broken (PR11642).
IMPORTANT: If you're doing incremental builds you may get tons of
linker warnings. make clean will fix them.
