async functions have error return traces where appropriate
...
however the traces are not merged on `await` or async function calls
yet.
When an async function has an error set or error union as its return
type, it has a `StackTrace` before the args in the frame, so that it is
accessible from `anyframe->T` awaiters. However when it does not have an
errorable return type, but it does call or await an errorable, it has a
stack trace just before the locals. This way when doing an `@asyncCall`
on an async function pointer, it can populate the args (which are after
the `StackTrace`) because it knows the offset of the args based only on
the return type.
This sort of matches normal functions, where a stack trace pointer could
be supplied by a parameter, or it could be supplied by the stack of the
function, depending on whether the function itself is errorable.

add -Wno-pragma-pack when targeting windows-gnu
...
windows.h has files such as pshpack1.h which do #pragma packing,
triggering a clang warning. So for this target, this warning is
disabled.
this commit also improves the error message printed when no libc can be
used, printing the "zig triple" rather than the "llvm triple".
