i965: Add an INTEL_DEBUG=submit option for printing batch statistics.
When a batch is submitted, INTEL_DEBUG=bat prints a message indicating which part of the code triggered the flush, and some statistics about the batch/state buffer utilization. It also decodes the batchbuffer in debug builds...which is so much output that it drowns out the utilization messages, if that's all you care about. INTEL_DEBUG=submit now just does the utilization messages. INTEL_DEBUG=bat continues to do both (as the message is a good indicator that we're starting decode of a new batch). v2: Rename from "flush" to "submit" (suggested by Chris) because we might want "flush" for PIPE_CONTROL debugging someday.
