Update llvm-38 to release tarball, remove subversion dependency

[sierkb@…]

LLVM 3.8.0 release has been officially announced on Mar 08 2016: ​http://lists.llvm.org/pipermail/llvm-announce/2016-March/000067.html.

Download LLVM 3.8.0 sources and several prebuild binaries ​http://www.llvm.org/releases/download.html#3.8.0

Since official stable source tarballs are now available from the project's website, there seems no need to further use the svn checkout. Therefore, please change the svn checkout in favor to the official provided tarballs and so remove the subversion dependency. As done on all other previous stable llvm ports before.

Yeah, I’ll get around to this eventually. Note that the revision we currently have is newer than the 3.8.0 tags, so we’ll need to grab some patches off the branch or just wait until 3.8.1 to do this.

Replying to jeremyhu@…:

Just do it. :) The already existing patch file list and the bunch of existing patches in the ports files section do exist anyway, a maybe handful additional patches (or how many additional patches would that be) won't hurt. :)

or just wait until 3.8.1 to do this.

That could take long. When estimated? 3.8.0 just is released, so it could take a while, until 3.8.1 will be released.

The only extra patch that I care about is the change for ​https://llvm.org/bugs/show_bug.cgi?id=19422

If you want to provide a patch to the port that makes the changes and includes that upstream change, it would certainly help. I am swamped with other work and won't likely get to this for some time.
