It turned out the stall was an infinite loop that was the result of broken

I found an issue with the shader compiler for Cayman when I looked
into why the ext_transform_feedback/order test case caused a GPU stall.
It turned out the stall was an infinite loop that was the result of broken
calculation in the shader function. The issue is that Cayman uses the
tgsi_umad
The tgsi_umad function does not work for Cayman since it does not
populate the y, z and w slots for UMUL that Cayman requires.
