Using a single ID 'IntelLLVM' for the suite of Intel compilers based on the LLVM backend. The 'IntelLLVM' ID are used for C, C++, and Fortran. Data Parallel C++ will be handled in a separate commit. The C and C++ definitions are based on the Clang definitions. The Intel LLVM-based C and C++ compilers are based on the Clang front end, so existing Clang options are more likely to be a good match than options for the older Intel compilers. Fortran is based on the older Fortran front end with the LLVM backend. It has a similar interface to the older versions, though many options are shared with the C and C++ compilers. Fixes: #21561 Signed-off-by: William R. Dieter <william.r.dieter@intel.com>
