Only rewind destructuring assignments if we actually preparsed the arrow function. For the case of single-expression bodies, we don't preparse, but we were previously erroneously rewinding.

New test262 tests bring up a couple cases with async arrow functions that V8 didn't seem to handle properly; this patch makes those cases errors: - async (...x,) => y -- Rest parameter must be last formal parameter - async (...x = z) => y -- No default value for rest parameter - async (...x, y) => z -- Rest parameter must be last formal parameter Bug: v8:4483, v8:5051 Change-Id: I024d9ba0c854e8e5e75283df2ee53127b1be090d Reviewed-on: https://chromium-review.googlesource.com/496057 Commit-Queue: Daniel Ehrenberg <littledan@chromium.org> Reviewed-by: Adam Klein <adamk@chromium.org> Reviewed-by: Caitlin Potter <caitp@igalia.com> Cr-Commit-Position: refs/heads/master@{#45116}

This patch implements the runtime semantics of dynamic import. We create a new ASTNode so that we can pass the JSFunction closure() to the runtime function from which we get the script_url. d8 implements the embedder logic required to load and evaluate the modules. The API is mostly implemented as specified. BUG=8:5785 Review-Url: https://codereview.chromium.org/2703563002 Cr-Commit-Position: refs/heads/master@{#44551}

https://codereview.chromium.org/2694003002/ introduced "SyntaxError: Lexical declaration cannot appear in a single-statement context" for the case when let + desctructuring from a list happen. As was pointed out in https://codereview.chromium.org/2694003002/#msg18, the case without destructuring would also benefit from a better message: if a single statement is expected and "let identifier = ..." is seen, the error is indeed again that the lexical declaration is not a statement. However, the current error is "Unexpected identifier", because the parser tries to accept "let" as an identifier in an expression statement, and then gives up seeing the other identifier after "let". This CL ensures that the parser recognises the error properly and reports accordingly. It also renames the existing test, which contains destructuring, and adds the one with a non-destructuring lexical declaration.

ES2017 forbids the sequence of tokens "let [" in in expression statements [1]. This CL makes ParserBase report those instances as SyntaxError. It also adds a customised error message for that, because the standard "Unexpected token" is not applicable: "let" itself is not forbidden in those context, only the sequence of "let [".

The bug was caused by AstTraversalVisitor refactoring: https://codereview.chromium.org/2169833002/ InitializerRewriter::VisitRewritableExpression in parser.cc didn't recurse; so it fails when a rewritable expression contains another rewritable expression. See the bug for more details. BUG=chromium:679727 Review-Url: https://codereview.chromium.org/2629623002 Cr-Commit-Position: refs/heads/master@{#42274}
