Kepler and Tahiti Scheduling

Hi, thanks.

This point was quite annoying to me since alot of time, as it was not documented (or at least I could not find it in ISA or elsewhere). And I didnt like to have a ? there. yes, the register usage is documented quite decently, but not the PC/Flags/Stack one.

Execution mask, stack and condition flags are stored in registers, no need to save them when switching to another wavefront.
