UnlinkedFunctionExecutable should store SourceCode instead of offsets

• Component: JavaScriptCore
• Status: RESOLVED WONTFIX

[Ryosuke Niwa]

UnlinkedFunctionExecutable stores various offsets relative to its owner executable.
Just store SourceCode instead. For one extra pointer, we get a lot more clarity.
If the size is a concern, we can bit-pack two enums better.

This won't work because parsing from global code via cache would require us to adjust the source provider as well as line number and columns to be adjusted each time we link.
