[Mesa-dev] [PATCH 2/2] gallium/ddebug: regularly log the total number of draw calls

This helps in the use of GALLIUM_DDEBUG_SKIP: first run a target application
with skip set to a very large number and note how many draw calls happen
before the bug. Then re-run, skipping the corresponding number of calls.
Despite the additional run, this can still be much faster than not skipping
