[PATCH] D47982: Fix when LLVM_USE_INTEL_JITEVENTS and LLVM_USE_OPROFILE not set, llvm-build not gen LibraryDependencies.inc

If LLVM_USE_INTEL_JITEVENTS and LLVM_USE_OPROFILE  not set,  "${LLVMOPTIONALCOMPONENTS}" is empty, but  **--enable-optional-components** need arg, Cause **--write-library-table** to be skipped parsed.

My CMake version: 3.11.2

  cmake
  execute_process(
    COMMAND ${PYTHON_EXECUTABLE} -B ${LLVMBUILDTOOL}
              --native-target "${LLVM_NATIVE_ARCH}"
              --enable-targets "${LLVM_TARGETS_TO_BUILD}"
              --enable-optional-components "${LLVMOPTIONALCOMPONENTS}"
              --write-library-table ${LLVMCONFIGLIBRARYDEPENDENCIESINC}
              --write-cmake-fragment ${LLVMBUILDCMAKEFRAG}
              OUTPUT_VARIABLE LLVMBUILDOUTPUT
              ERROR_VARIABLE LLVMBUILDERRORS
              OUTPUT_STRIP_TRAILING_WHITESPACE
              ERROR_STRIP_TRAILING_WHITESPACE
    RESULT_VARIABLE LLVMBUILDRESULT)
