Jay Foad 3ec208e13e [AMDGPU] Use divergent addresses for vector loads 
Change some test cases to use divergent addresses for vector loads,
which should be the common case in real world code. Using uniform
addresses causes poor instruction selection for the surrounding
code which has to be fixed up post-register-allocation, and this causes
a lot of testsuite churn for a forthcoming patch to stop selecting
24-bit vector multiply instructions for uniform multiplies.

This shows up some problems in the idot tests where we fail to select
v_dot instructions because the patterns only match MUL_[UI]24 ISD nodes,
but the DAG contains i16 mul nodes instead.
