These flags have been on by default since version 4.9, which has been
in stable Chrome for over a week now, demonstrating that they're
here to stay.

Also moved the tests out of harmony/ and into es6/.

This is in preparation for the addition of --harmony-destructuring-assignment.

This requires copying usage flags from the outer scope to the
arrow scope upon encountering the arrow token.

In order to properly pass-on the calls_eval bit, now record
that bit on script scopes just like everywhere else, and add
necessary code to scopes.cc to handle that change in behavior.

Also factored out scope flag propagation to its own method to
make the call site simple (though note that only the eval
bit makes any difference for arrows).

Add() becomes AddLocalExport, which takes an export_name and a local_name.
New parsing tests exercise this.

Also start generating exports for default exports (though this doesn't yet
handle anonymous default exports).

Adding the line "// MODULE" to an mjsunit file will now cause
run-tests.py to prefix the test case with "--module" in the
d8 commandline.

d8 has itself been updated to treat files preceded with "--module" as
modules (that is, it compiles them with ScriptCompiler::CompileModule,
and turns on --harmony-modules).

This is to avoid triggering an assertion from Smi::FromInt. The
generated code is unreachable, so it is not a real bug.
