This patch enables the Fortran runtime support library to be
built without native 128-bit integer support in the C++ compiler.

Experimental: do not merge yet.

Just for context (w.r.t. approval), from llvm/llvm-project#63712

@h-vetinari: WDYT about backporting this to 17.x? Should not be too invasive I think...? If you agree, could you add it to the milestone?

@klausler: Go ahead if you want to. I don't have any time for this.

Is this safe and critical enough to go into final?

I'm confident to say it's safe. It doesn't change the default case, but unbreaks those who don't have native 128bit types (=windows) and thus need AVOID_NATIVE_UINT128_T. We've been shipping it in conda-forge by necessity, and it builds & runs fine.
