[llvm] Emit float128 libcalls for some F128 variants (PR #79611)

[Pranav Kant via llvm-commits]

https://github.com/pranavk created https://github.com/llvm/llvm-project/pull/79611

Make LLVM emit libcalls to proper float128 variants for float128 types.

There are many other variants that may require this change. I am just putting this out for now to enable it for simple functions that are blocking me.
