Fix parsing of string literals.

String literals can be used as part of attributes, but we lacked an actual AST representation for them.
This change adds basic parsing for string literals, as well as emit logic for them.

I also included a fix for parsing of chained right-associative operators.

To test these fixes, I've re-enabled one of the HLSL tests I disabled a while back. It would be good to go through and see how many of those we can re-enable now.
