Restore lldb build

[tromey]

commit 6c10142 ("Update LLVM submodule") disabled the lldb build.
This patch updates the lldb and clang submodules to once again build
against the LLVM that is included in the Rust tree, and reverts the
.travis.yml changes from that patch.

Done. Your build exited with 1.

I'm a bot! I can only do what humans tell me to, so if this was not helpful or you have suggestions for improvements, please ping or otherwise contact @TimNN. (Feature Requests)

[tromey]

The lldb code definitely looks incorrect -- that file has moved -- but I cannot reproduce it in a local build.

[tromey]

Maybe locally it is picking up an installed lldb header.

[tromey]

I've fixed the lldb issue and as it is trivial I'm going to see if I can re-r+ this.
