Title: Change on_vasgn to more precise on_lvasgn

This change means that only local variables are put into the current
scope (not global, instance, and class ones). This is how it should be.

Note the change doesn't change visible behavior because:

1. All variable types previously stored in the scope had unique
prefixes ("@", "@@", or "$"), which means they didn't conflict with
local variables also stored there. The scope just contained
additional incorrect information.

2. We check for variable type in "nice_variable", meaning the
additional incorrect information stored in the scope didn't affect
anything.
