adamk 7166503f6e Do all parsing for try/catch destructuring inside the appropriate scopes
Previously, any expressions inside destructuring patterns in a catch
would be parsed in the surrounding scope, instead of in the catch's
scope. This change fixes that by entering not only the catch scope,
but also the block scope inside it.
