     Ignore stdcall c-call in native codegen on x86_64

     The stdcall calling convention is not supported on x86_64.
     When an ffi import requests stdcall, a warning is issued as
     desired by #3336. However, the native codegen was still
     generating code that expected the callee to cleanup the
     stack arguments when calling a c function that requests
     stdcall.

     This patch changes the codegen to actually use the ccall
     calling convention as intended.
