r600_get_name never gets called for me in Xorg while running your test case.
Even in the unlikely case that it's really getting called for you,
eliminating it completely could only increase performance by about 5% at
most, which wouldn't make any significant difference compared to the
order of magnitude performance difference between glamor and SNA.
