HLSL: Wrap the entry-point; need to write 'in' args, and support 'inout' args.

Browse source 
This needs some render testing, but is destined to be part of master.

This also leads to a variety of other simplifications.
 - IO are global symbols, so only need one list of linkage nodes (deferred)
 - no longer need parse-context-wide 'inEntryPoint' state, entry-point is localized
 - several parts of splitting/flattening are now localized
