Named export

[neumatho]

Hi,

It seems that Meriyah does not comply with the AST standard when having named export, e.g. export * as x from 'a'.

First of all, it creates a ExportNamedDeclaration where it stored an ExportNamespaceSpecifier in the specifiers array. The last one is unknown according to the specifications. If you compare it to Acorn, which seems to do it the right way, then you should create an ExportAllDeclaration and then set the exported property to 'x'.

If you look at the specifications, then you will see that this is the correct way to do it:

This looks like a new change in syntax. estree/estree#202

FYI @babel/parser still does the old way like us. I will update our implementation.
