bits of software and to use a modern GCC version.

The Subversion bit was weird anyways -- it has nothing to do with
compiling LLVM. Also, there are many other ways to get at the trunk
source (git, git-svn, etc).

The TeXinfo thing... I have no idea about. But you can get a working
LLVM w/o it pretty easily. If man pages or something are missing, that
hardly seems like a problem. If folks really want this back, let me
know, but it seems mostly like a distraction.

I'd still like to separate this into:
- Required software to compile.
- Optional software to compile.
- Required software for certain *contributor* activities (like
  regenerating configure scripts).

Also we need to mention that there are multiple options for build
systems, and the differences.

Also we should mention Windows.

Also probably other stuff I'm forgetting.

I'm wondering if this whole thing needs to be shot in the head and we
should just start a new, simpler getting started that doesn't have so
many years of accumulated stuff that is no longer relevant.

actually looks like the table on the webpage and is entertainingly
smaller, easier to read, and easier to edit.

getting started guide.

Some highlights:
- I heard there was this Clang compiler that you could use for your
  host compiler. Not sure though.
- We no longer have a GCC frontend with weird build restrictions.
- Windows is doing a bit better than partially supported.
- We nuked everything to do with itanium.
- SPUs? Really?
- Xcode 2.5 and gcc 4.0.1 are really not a concern -- they don't work.
- OMG, we actually tried building LLVM on Alpha? Really?
- PowerPC works pretty well these days.

There is still a lot of stuff here I'm pretty dubious about, but I nuked
most of what was actively misleading, out of date, or patently wrong.
Some of it (mingw stuff especially) isn't really lacking, its just that
the comments here were actively wrong. Hopefully folks that know those
platforms can add back correct / modern information.

Summary:
Fixes an issue where a test attempts to use -mcpu=x86-64 on non-X86-64 targets.
This triggers an assertion in the MIPS backend since it doesn't know what ABI to
use by default for unrecognized processors.

With this change, one may set LLVM_BUILD_EXTERNAL_COMPILER_RT option
to build compiler-rt libraries with just-built Clang.

  make compiler-rt
in the build tree will build all compiler-rt libraries with just-built Clang
and copy them to the proper location in the Clang resource directory.

  make check-compiler-rt
will run the compiler-rt test suite using just-built Clang and runtime
libraries.

The goal is to make LLVM_BUILD_EXTERNAL_COMPILER_RT the default, so that
we can always build compiler-rt libraries with Clang, not the host compiler,
and for all the platforms Clang can target.

asan_device_setup is a utility that prepares a device to run code built with
ASan. Essentially, it installs ASan runtime library into the system. For this
reason, it has to be at a predictable relative path from the runtime library
itself. We also plan to distribute this utility, packaged with runtime library
and maybe llvm-symbolizer, to the users.

With r197755 we started reading the contents of buffer file entries, but the
buffers may point to ASTReader blobs that have been disposed.

Fix this by having the CompilerInstance object keep a reference to the ASTReader
as well as having the ASTContext keep reference to the ExternalASTSource.

This was very difficult to construct a test case for.

If the SI_KILL operand is constant, we can either clear the exec mask if

This test also illustrates that checking for properties is not working properly with
this attribute, as we are missing a diagnostic for a property not being implemented.
