The intrinsic module IEEE_ARITHMETIC must incorporate the public names from the intrisic module IEEE_EXCEPTIONS. Rename IEEE_EXCEPTIONS to __Fortran_ieee_exceptions so that it won't clash with the nonintrinsic namespace, establish a new intrinic IEEE_EXCEPTIONS module that USEs it, and add a USE to IEEE_ARITHMETIC. Updated to use STREQUAL rather than ambiguous MATCHES in the CMakeLists.txt file. Differential Revision: https://reviews.llvm.org/D121490
