Update to clang-3.8.0. Split out llvm tools to lang/llvm.

Packaged in pkgsrc-wip by myself and Kamil.
Remove stale pkgsrc/SunOS bread crumbs that were difficult to merge
following the build framework switch. Needs to be redone. (Sorry!)

Summary of significant changes in LLVM:
- switch build framework from autoconf to CMake
- llvm-ar now supports thin archives.
- llvm doesn t produce .data.rel.ro.local or .data.rel sections anymore.
- opional support for linking clang and the LLVM tools with a single
  libLLVM shared library

  pkgsrc note: we have this library in lang/libLLVM, but we don't currently
  use it. We may do so in the future if/when the API matures.

- The optimization to move the prologue and epilogue of functions in colder
  code path (shrink-wrapping) is now enabled by default
- new target-independent gcc-compatible emulated Thread Local Storage mode
- various target specific optimizations

Summary of significant changes in Clang:

- new compiler flags for tuning what DWARF information is included
- better strict alignment handling
- better support for __builtin_object_size
