[Mesa-dev] [PATCH v2 11/23] glsl/tests/optimisation-test: ensure that compare_ir is available

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

Bail out early if the script is not where we expect it to be.

v2: use -f instead of -e. latter returns true on folder(s)

Eric, -r does not distinguish between files and folders so I've changed
to -f and removed your r-b. I think as-is it addresses your comment,
right ?
