This is something I sometimes want to do in testing, to see if a
mystery bug (say, 29172) is due to broken clock gating. Sadly, in
this case it isn't. Note that it isn't supported on non-ILK chipsets
yet.

Add four new tests for error the error handling cases:
- gem_bad_address - store to a bad address, should generate a protection or
page table error
- gem_bad_batch - try to execute a bad batch, should generate a protection,
invalid instruction or page table error
- gem_bad_blit - blit to an invalid location, should generated a protection
or page table error
- gem_hang - hang the GPU on an event that will never happen, test hang
detection & recovery code
