Additional semantic checking for tessellation shaders and related clean up:

- non-arrayed geometry inputs and tessellation-control outputs
 - include user blocks in i/o array resizing based on primitive type
 - things belonging only to 'in' or 'out' are verified only on 'in' or 'out'
 - invocation number changing
 - move shader-scoped qualifier checking into its class
 - remove an incidental union of two levels of the node hierarchy in the yacc stack
 - remove layout(location=) default tracking when setting on a variable
