recipes: Rework llvm/clang/compiler-rt/libcxx/lldb recipes

This is an overhaul of clang/llvm project related recipes

* switch to using a flat mono repo for all clang/llvm projects
* Add llvm-project-source recipe which will prepare source tree in
  work-shared for all recipes much like kernel and gcc
* build lld as part of clang recipes, its much easier and saves build
  time and hopefully nativesdk version will be built now for free
* switch to official git repos at git://github.com/llvm-project
* Adjust all recipes to use shared sources

- llvm-config.
-
-    Note: AddLLVM.cmake does not expose the LLVM source directory.
-    So if you want to run the test suite, you need to either:
-
-    1) set LLVM_MAIN_SRC_DIR explicitly (to find lit.py)
-    2) change AddLLVM.cmake to point to an installed 'lit'.
-    3) add_subdirectory(compiler-rt/test) from clang instead of compiler-rt.

-Subject: [PATCH 4/5] cmake/mips: Do not specify --target with OE
-
-OE already specifies cross compiler correctly, adding this additional
---target confuses the clang driver and it resorts to invoke host assembler
-when using -no-integrated-as
-
-Fixes errors e.g.
-|   Assembler messages:
-|
-|   Fatal error: invalid -march= option: `mips32r2'
-|
-|   clang-4.0: error: assembler command failed with exit code 1
