When llvmpipe is allowed execute fragment shaders overlapping
with other stuff, we have to start using the pipe fences.
With presentation, the acquire path needs to signal a semaphore
that can be waited on by the user, so add support for passing
signal/wait semaphores for non-timeline in, and just put a
fence pointer in the semaphore for that case.
This fixes rendering once we allow overlapping rasterization.
