Now most packages in the llvm suite are built as separate derivations.
The exceptions are:
* compiler-rt must currently be built with llvm. This increases llvm's
size by 6 MB
* clang-tools-extra must be built with clang
In addition, the top-level llvm attribute is defaulted to llvm 3.4, and
llvm 3.3 must be accessed by the llvm_33 attribute. This is to make the
out-of-date packages obvious in the hope that eventually all will be
updated to work with 3.4 and 3.3 can be removed. I think we should keep
this policy in the future (latest llvm gets top-level name, the rest are
versioned until they can be removed).
The llvm packages (except libc++, which exception I will try to remove
on the next update) can all be accessed via the llvmPackages attribute,
and there are also aliases for the packages that already existed (llvm,
clang, and dragonegg).

Some packages in the llvm suite (e.g. compiler-rt) cannot be built
separate from the build of llvm, and while some others (e.g. clang) can
the combined build is much better tested (we've had to work around
annoying issues before). So this puts llvm, clang, clang-tools-extra,
compiler-rt, lld, lldb, and polly all into one big build (llvmFull).
This build includes a static llvm, as dynamic is similarly less tested
and has known failures.
This also updates libc++ and dragonegg. libc++ now builds against
libc++abi as a separate package rather than building it during the
libc++ build.
The clang purity patch is gone. Instead, we simply set --sysroot to
/var/empty for pure builds, as all impure paths are either looked up in
the gcc prefix (which we hard-code at compile time) or in the sysroot.
This also means that if NIX_ENFORCE_PURITY is 0 then clang will look in
the normal Linux paths by default, which is the proper behavior IMO.
polly required an updated isl. When stdenv-updates is merged, perhaps we
can update the isl used by gcc and avoid having two versions.
Since llvm on its own is now separate from the llvm used by clang, I've
removed myself as maintainer from llvm and will leave maintenance of
that to those who are interested in llvm separate from clang.

Instead of applying all of the patches, this build pulls an archive from
the source code repo with all of the patches already applied. This is the
preferred way from http://www.vim.org/sources.php
* Remove package name
* Start with upper case letter
* Remove trailing period
Also reword some descriptions and move some long descriptions to
longDescription.
I'm not touching generated packages.
