When the anytype parameter had only one-possible-value
(e.g. `void`), it would create a mismatch in the function type and the
function call. Now the function type and the callsite both omit the
one-possible-value anytype parameter in instantiated generic functions.
This small change makes working with tuple types much easier, allowing
the use of anonymous (eg. obtained with meta.ArgsTuple) tuples in more
places without the need for specifying each (quoted!) field name in the
initializer.

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.
