[Piglit] [PATCH 0/2] V4: SSO: new test to ensure correct deadcode optimization

[Gregory Hainaut]

Related to mesa issue: https://bugs.freedesktop.org/show_bug.cgi?id=79783

Mostly "Validated" on Nvidia driver. Nvidia fails to link vs_fs_prog_separate_inactive on first test

v4:
* Add both test to all.py

v3:
* Add a new test to ensure matching with various qualifier
To be discussed. I don't know, if behavior is acceptable/legit for version below GLSL4.5

v2:
* Test both output and input are still active
* Test real interstage variable are still optimized
* Mix rendezvous by name and location
