Tweak TypeVariablesMap attribute to mention enclosing contexts.
* Change the structure of the TypeVariableMap, so as to contain a list of entries,
each of which corresponds to a lexically enclosing scope declaring some type-variables. This allows
for fast type-variable lookups, which can be achieved w/o looking into InnerClass and EnclosingMethod attributes.
