[igt-dev] [PATCH i-g-t v3 3/4] scripts/test_list.py: use a compiled regex for check

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

Speed up even further the logic for --check-testlist by
pre-compiling the regex that will be used to validate the
results.
