Clang currently passes and returns `__float128` in vector registers on MinGW

I'm struggling a bit with how to handle ABI information since that affects

Currently `fp128` math intrinsics are lowered to functions expecting `long
double`, which is a problem when `long double` and `f128` do not have the same
layout (e.g. `long double` on x86 is `f80`).
