Before this change, when we encounter a constant cache that is specific to a lexical scope, we unconditionally exit. This change falls back to the interpreter's cache in this situation.
This should help constant expressions in class << self, which is popular at Shopify due to the style guide.
This change relies on the cache being warm while compiling to detect the need for checking the lexical scope for simplicity.
