[Intel-gfx] [PATCH i-g-t] tests/initial_state: Add a test to capture the state of the GPU

[Martin Peres]

The commit name "Add a test to capture the state of the GPU" should 
likely be renamed to "Add a test that checks the current state of the 
driver".

This is not mandatory, but how about adding:

"When coupled with piglit's abort-on feature, this makes the piglit 
results contain the reason for the abort when the driver's initial state 
is unacceptable, improving debuggability"

With the commit title and the typo fixed, the patch is:
