hsail gate commands

[Deneau, Tom]

Doug --

I noticed in syncing with the trunk as of last Friday that all of our HSAIL test cases broke.  The cause was some imperfect code in our HSAILAssembler for compare instructions which when presented with an unordered compare could generate code that would not assemble, and was easy to fix.

But I was wondering how this made it past the gate.
Can you describe what gate commands are used regarding hsail?
