In 2acf77f987331c05520c5bfd849326909ffce983 code was added to use the 'full' name including syntax and scope. Instead of building up a large string for each name, add syntax and scope checks to the value expression in tablegen. There is already code to generate expressions for target specific attributes. This change refactors and adds to that code to include syntax and scope checks. The tablegen avoids generating the complicated expression unless there are two attributes using the same name, otherwise the case values will be as simple as before. Removes the currently unused attributeHasStrictIdentifierArgAtIndex function and the related tablegen.
