1591209 - Add JSFunction::baseScript()

Status: RESOLVED FIXED

(Core :: JavaScript Engine, task, P1)

Description

[Ted Campbell [:tcampbell]]

In order to move towards JSFunction not storing the LAZY_INTERPRETED flag, it is helpful to add a JSFunction::baseScript accessor when the info being queried is defined on either. This also means we can avoid forcing delazification in cases we don't care about and reserve it for cases that we do (such as being ready to execute).
