Those Bash scripts aren't used anywhere by the meson build.

However, the Python scripts that they run are:

* src/compiler/glsl/tests/optimization_test.py
* src/compiler/glsl/glcpp/tests/glcpp_test.py

Both are run directly (they are executables), and their shebang is
Python 2. :-/

They just aren't hooked up using prog_python like all the build
scripts, so I indeed completely missed them.

Are you already porting them over? Otherwise I'll try to have a look
