Nicolai Haehnle 4821937d2e AMDGPU: Avoid selecting ds_{read,write}2_b32 on SI 
Summary:
To workaround a hardware issue in the (base + offset) calculation
when base is negative. The impact on code quality should be limited
since SILoadStoreOptimizer still runs afterwards and is able to
combine loads/stores based on known sign information.

This fixes visible corruption in Hitman on SI (easily reproducible
by running benchmark mode).
