volatile thread seems like it's asking for trouble with spilling. volatile thread is somewhat meaningless. I know this comes up because in later SPIR-V discard + helper lane is done through volatile StorageClassInput.

Do you think we should just avoid volatile on thread variables in general?

One of our tests only passed because it operated out of the entry point and would fail if you tried to do the same thing from any other function. This makes it work no matter where it is.
Note: I couldn't think of any better names for the new variable than just adding an underscore. If anyone else has a better name, please use it.
