r600: implement callstack workaround for evergreen.
This is ported from the sb backend, there are some issues with
evergreen stacks on the boundary between entries and ALU_PUSH_BEFORE
instructions.
Whenever we are going to use a push before, we check the stack
usage and if we have to use the workaround, then we switch to
a separate push.
I noticed this problem dealing with some of the soft fp64 shaders,
in nosb mode, they are quite stack happy.
This fixes all the glitches and inconsistencies I've seen with them
