commit 13a54882ce2a67bf54794079ba3c928985db8b1e

    coverage: Misc Javascript-side API changes
    
    Debugger.Script.getOffsetLine() which we previously used in code coverage
    is gone now, replaced by Debugger.Script.getOffsetLocation() which gives
    more information. We don't currently take advantage of the extra
    information.
    
    ArrowExpression was renamed to ArrowFunctionExpression.
