[PATCH v2 0/1] MR499: tests: Print the line number of the probe when a test fails.

[Petrichor Park (＠petrathekat)]

Currently, if a probe fails, it will print the line number of the [test]
block the probe is in, not the line number of the probe itself. This
makes it somewhat difficult to debug.

This commit makes it print the line number of the probe as well.

Right now this prints both the line where the section starts and the line there the `probe` directive here. This feels a bit too much.

Honestly it'd probably be sensible to use ok_() to print "whatever.shader_test:123:Test failed"

Though notice that, as it is now, `ok_()` only takes the line number, so it prints `shader_runner` instead of `whatever.shader_test`.
