  Changed paths:
    M llvm/cmake/modules/HandleLLVMOptions.cmake
    M llvm/cmake/modules/LLVMExternalProjectUtils.cmake
    M llvm/docs/CMake.rst

  Log Message:
  -----------
  [CMake] Enable the use of -ffile-prefix-map

This handles not paths embedded in debug info, but also in sources.
Since the use of this flag is controlled by an option, rather than
replacing the new option, we add a new option.

  Changed paths:
    M clang/cmake/caches/Fuchsia-stage2.cmake

  Log Message:
  -----------
  [Fuchsia] Use -ffile-prefix-map

This makes toolchain independent of the path it was built in by
rewriting all absolute paths embedded in sources and debug info
into relative ones.
