This patch registers the 've' target: the NEC SX-Aurora TSUBASA Vector Engine.

This follows up on the announcement on llvm-dev: https://lists.llvm.org/pipermail/llvm-dev/2019-April/131580.html
We have a poster & lightning talk at the upcoming DevMtg: http://llvm.org/devmtg/2019-10/talk-abstracts.html#lit6

- Public documentation (architecture, encodings, instructions)
  - ISA manual: https://www.hpc.nec/documents/guide/pdfs/Aurora_ISA_guide.pdf
  - Up-to-date documentation on architecture and tools: https://www.hpc.nec/documents/

- Reference implementation
  - github: https://github.com/sx-aurora-dev/llvm-project
  - Status: full scalar instruction support, clang toolchain integration, vector support through intrinsics.

- Testing
  - Reference implementation is tested continuously at NEC.
  - We are planning to setup a buildslave reporting to LLVM buildmaster.

- Code owner of the VE target
  - Simon Moll

A rough roadmap:

1. Registers, encodings, scalar instructions, clang tooling, ..
2. Vector instruction support through target-specific intrinsics.
3. Support for LLVM-VP <https://reviews.llvm.org/D57504> as it becomes available in LLVM upstream.
