Compiler crash when declaring methods on arrays of distinct type

[cbuttner]

This asserts with ⚠️ The compiler encountered an unexpected error: "Violated assert: type->decl->resolve_status == RESOLVE_DONE".:

distinct Foo = int;
fn void Foo[2].foo(&self) {}
// Same with:
macro Foo[2].bar(&self) {}

I'm not on the latest commit so please ignore if this has already been fixed.

This should be fixed now.
