This change completes support for import assertions for dynamic import(). A new version of the HostImportModuleDynamically callback taking import assertions is added to the public API. The name is very verbose; we could consider removing the "ImportAssertions" part when the old API is removed. Bytecode generation is updated to pass the assertions, if present, to Runtime_DynamicImportCall. Isolate::RunHostImportModuleDynamicallyCallback extracts the assertions from the options bag, filters out the assertions not present in the list specified by the host in HostGetSupportedImportAssertions, and sorts them by code point order of the keys per https://tc39.es/proposal-import-assertions/#sec-import-call-runtime-semantics-evaluation. The resulting array is passed to the host in the callback.

d8 treats files with the .mjs extension as modules instead of classic scripts. Thus, the `// MODULE` pragma and its corresponding logic in test runners can be removed in favor of explicitly adding the extension.

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}
