From: Mauro Carvalho Chehab <mchehab at kernel.org>
Currently, even a single change on IGT makes the build time too
slow.
This is because it will re-generate the check testlist on every
single build that touches any file.
Change the logic to generate per-file testlists, with speeds up
build time from 22 seconds to 4 seconds.
It can be improved even further after changing the build logic
to maintain separate test_executables for i915, kms and xe.
As there's a pending patch series touching those tests, moving
them to tests/intel directory, let's not do a conflicting change.
Once such patch series gets merged, I'll write a patch with the
pending optimization.

v2:
- make it compatible with Meson 0.47;
- added a patch to simplify tests/meson.build
- dropped a change at gem_stress - maybe there's a real reason
why this one was excluded from test_list, so let's keep it
as-is.
Mauro Carvalho Chehab (5):
tests/meson.build: Simplify builds for core and i915 targets
lib/igt_core: use the macro when checking for list_subtests
lib/igt_core: add an option to show the testlist
tests/meson.build: create testlists for tests
scripts/test_list.py: speedup testlist check logic
