Clang 12 fails to build Flang with `-DWITH_WERROR=ON`
Setting the CMake variable WITH_WERROR=ON tells Clang to compile Flang code with -Werror, which turns compile-time warnings into fatal errors. This had to be turned off by default in b8b491466da3 since LLVM 12 now produces many more warnings than previous LLVM versions.
I will submit a number of PRs to fix the Flang code base, in order to reduce the number of compile-time warnings, and enable WITH_WERROR=ON to be used again. Some problems requiring more extensive changes will be considered in future issues.
