Defined I/O subroutines have UNIT= and IOSTAT= dummy arguments that are required to have type INTEGER with its default kind. When that default kind is modified via -fdefault-integer-8, calls to defined I/O subroutines from the runtime don't work. Add a flag to the two data structures shared between the compiler and the runtime support library to indicate that a defined I/O subroutine was compiled under -fdefault-integer-8. This has been done in a compatible manner, so that existing binaries are compatible with the new library and new binaries are compatible with the old library, unless of course -fdefault-integer-8 is used. Fixes https://github.com/llvm/llvm-project/issues/148638.
