BPF Goes Through With Becoming An Official LLVM Back-End

Earlier this week I wrote about the BPF back-end seeking a promotion in LLVM to officially become a first-class back-end. The feedback was positive and now for LLVM 3.7 the BPF back-end is official.

BPF is serving as an in-kernel virtual machine with Clang serving as the de facto compiler thus far for targeting the BPF representation. BPF has been evolving a lot over the recent kernel releases while more kernel-side improvements are coming.

With this commit, the BPF back-end is no longer experimental within LLVM and thus will be built by default for more users.
