Topic: plans for windows fastcall and new backend x64

Currently I'm hitting a panic at get_intreg_for_arg_systemv in tests. ATM trying to add unwind info to Windows Fastcall. What are the plans for this call convention?

Cranelift: implement WindowsFastcall in VCode · Issue #2372 · bytecodealliance/wasmtime
The issue is a part of #2079 (and possibly #1642 ?). The issue needs to be extended to all new backends (x64 and aarch64). This will require implementing the win64 fastcall ABI support in cranelift...

I would expect there to be a new function for windows fastcall rather than using the systemv specific get_intreg_for_arg_systemv.
