new piglit test max-texture-size2 to reproduce the problem

/ [AMD/ATI] Cape Verde PRO [FirePro W600] /

The piglit test max-texture-size2 prints:

GL_TEXTURE_RECTANGLE, Internal Format = GL_RGBA8, Largest Texture Size = 16384
radeon: Not enough memory for command submission.
[drm:radeon_cs_ioctl [radeon]] *ERROR* Failed to parse relocation -12! (ENOMEM)
PIGLIT: {"subtest": {"GL_TEXTURE_RECTANGLE-GL_RGBA8" : "pass"}}

It says it passes but internally it fails. It looks like a bug from the TTM GPU
memory manager subsystem in the linux kernel.

To reproduce just run:
RADEON_THREAD=false DISPLAY=:0 PIGLIT_SOURCE_DIR=/home/julien/dev/piglit/
PIGLIT_PLATFORM=mixed_glx_egl ./bin/max-texture-size -fbo -auto

I set RADEON_THREAD=false to make it easier since the problem also appears with
true.

I attached a new and more minimal piglit test "max-texture-size2" that
reproduces the problem.
A workaround of the problem is to use GL fence as the new test also
demonstrates setting the env var USE_FENCE.</pre>
