31aefa6a21 fix structs that contain types which require comptime 
Now, if a struct has any fields which require comptime,
such as `type`, then the struct is marked as requiring
comptime as well. Same goes for unions.

This means that a function will implicitly be called
at comptime if the return type is a struct which contains
a field of type `type`.

fcbb7426fa use * for pointer type instead of & 
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'
