Jay Foad c799f873cb [AMDGPU] Don't cluster stores 
Clustering loads has caching benefits, but as far as I know there is no
advantage to clustering stores on any AMDGPU subtargets.

The disadvantage is that it tends to increase register pressure and
restricts scheduling freedom.

Mirko Brkusanin 0654ff703d [AMDGPU] Use ds_read/write_b96/b128 when possible for SDag 
Do not break down local loads and stores so ds_read/write_b96/b128 in
ISelLowering can be selected on subtargets that support them and if align
requirements allow them.
