How to implement fastcall ?
( stdcall is calling convention for pass function arguments via 
registers )

The supported linkage attributes are here:

https://dlang.org/spec/attribute.html#linkage

`extern(Windows)` is stdcall, `extern(C)` is cdecl. Unless it's a 
hidden feature that I'm unaware of, fastcall is not supported.

Hypothesis: it is possible what LLVM + Link Time Optimization 
does by this way.

~All modern ABIs use registers; __fastcall was one of the special 
32-bit x86 ABIs AFAIK (using up to 2 GP registers) and isn't 
supported directly. The D ABI for 32-bit x86 uses one GP register 
(and is somewhat similar to __thiscall for member functions).
