tests: 4 fixes (glx, amd_performance_monitor, opengl.py and arb_texture_multisample)
- 1st commit fixes the 3 tests from amd_performance_monitor: they weren't reporting the global test result which makes piglit-runner believes they crashed
- 2nd commit cleans glx-make-current.c
fixes a GLX error inglx-make-current
(it doesn't prevent the random results I get but that's a first step) - 3rd commit: fixes a test binary name
- 4th commit: skip unsupported combination instead of reporting a failure
