Title: diakgcn update to output-buffer writing for -v 2 and higher

Hey Con,

This pull request needs a code-review, to be sure I broke nothing used by all other kernels. Goal here was to minimize the needed instructions for the outpur-buffer writing and I guess I achieved that goal.

The new code removes 1x s_waitcnt(), 1x tbuffer_store_format_x() (= 1 global write) and 2x s_cbranch_execz() instructions with the corresponding "jump-points" in the GPU ISA code on GCN, so should be a bit faster.
