Subject: [PATCH] LibJS: Parse only AssignmentExpressions in
 ComputedPropertyNames

The property name in an object literal can either be a literal or a
computed name, in which case any AssignmentExpression can be used, we
now only parse AssignmentExpression instead of the previous incorrect
behaviour which allowed any Expression (Specifically, comma
expressions).
