Four new tests for error handling

Browse Source 
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

/** @file gem_tiled_blits.c
*
* This is a test of doing many tiled blits, with a working set
* larger than the aperture size.
*
* The goal is to catch a couple types of failure;
* - Fence management problems on pre-965.
* - A17 or L-shaped memory tiling workaround problems in acceleration.
*
* The model is to fill a collection of 1MB objects in a way that can't trip
* over A6 swizzling -- upload data to a non-tiled object, blit to the tiled
* object. Then, copy the 1MB objects randomly between each other for a while.
* Finally, download their data through linear objects again and see what
* resulted.
