R600/SI: Add load / store machine optimizer pass.
Currently this only functions to match simple cases
where ds_read2_* / ds_write2_* instructions can be used.
In the future it might match some of the other weird
load patterns, such as direct to LDS loads.
Currently enabled only with a subtarget feature to enable
easier testing.
