Seems like a good "mean" test...I'd hate to debug it, but worth having. 
  I didn't review the details.

Kind of big for a "basic" test, but definitely seems worth having.

This one looks fine.

Please, please, please split these into separate tests.   Debugging 
shaders that have 'subtests' with switch statements is generally a royal 
pain.  In particular, when I bring up a new hardware platform, I often 
have to compare Gen X assembly to Gen X+1 assembly.  The smaller the 
shader, the easier that is.

The individual subtests look reasonable.

This test seems reasonable.  It could be split, but it's simple enough 
that I wouldn't object either way.
