Please reupload with fixed Nit and added test cases for arrow function body expressions that don't end in ";" and I will r+/cq+

> Source/JavaScriptCore/parser/ASTBuilder.h:375
> +        SourceCode source = m_sourceCode->subExpression(functionInfo.startOffset, functionInfo.body->isArrowFunctionBodyExpression() ? functionInfo.endOffset -1 : functionInfo.endOffset, functionInfo.startLine, functionInfo.bodyStartColumn);

Nit: space between "-" and "1"

> Source/JavaScriptCore/parser/ASTBuilder.h:376
>          ArrowFuncExprNode* result = new (m_parserArena) ArrowFuncExprNode(location, *functionInfo.name, functionInfo.body, source);

The - 1 worries me. 
Does this work:
function foo(x) { print(x.toString() }
foo((y)=>y)
