8b3a9205b7 R600/SI: Also try to use 0 base for misaligned 8-byte DS loads.

704b06ce61 R600/SI: Use DS offsets for constant addresses 
Use 0 as the base address for a constant address, so if
we have a constant address we can save moves and form
read2/write2s.

fc9fda5443 R600/SI: Change how DS offsets are printed 
Match SC by using offset/offset0/offset1 and printing
in decimal.

9bd1daf4b9 R600/SI: Match read2/write2 stride 64 versions

968e1f2f5b 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.
