[Mesa-dev] [PATCH v2 3/5] i965: Fix INTEL_DEBUG=state to work with 64-bit dirty bits.

This will keep INTEL_DEBUG=state working when we add BRW_NEW_* bits
beyond 1 << 31.  We missed doing this when widening the driver flags
from uint32_t to uint64_t.

NAK on "i965: Update dirty_bit_map::bit to be a uint64_t."
It wasn't sufficient to keep this working.  I've now actually created
bits 32 and 33, and verified that they are counted and printed correctly.
