Nicolai Haehnle c06bfa1daa AMDGPU: Treat texture gather instructions more like other MIMG instructions 
Summary:
Setting MIMG to 0 has a bunch of unexpected side effects, including that
isVMEM returns false which leads to incorrect treatment in the hazard
recognizer. The reason I noticed it is that it also leads to incorrect
treatment in VGPR-to-SGPR copies, which is one cause of the referenced bug.

The only reason why MIMG was set to 0 is to signal the special handling of
dmasks, but that can be checked differently.
