Description

[Tooru Fujisawa [:arai]]

bug 1317400 adds JSScript.preludeStart_/LazyScript.preludeStart_/FunctionBox.preludeStart, that points the beginning of the function.

>     //   function * f(a, b) { return a + b; }
>     //   ^          ^                        ^
>     //   |          |                        |
>     //   |          sourceStart_             sourceEnd_
>     //   |
>     //   preludeStart_

if we can use preludeStart_ for all places that currently uses sourceStart_, we can remove those members.

bug 1216630 renamed preludeStart_ to toStringStart_.

It looks like only the debugger really uses this, and they seem to really want toStringStart_.
