1f996fa36b R600/SI: Add a stub GCNTargetMachine
This is equivalent to the AMDGPUTargetMachine now, but it is the
starting point for separating R600 and GCN functionality into separate
targets.

It is recommened that users start using the gcn triple for GCN-based
GPUs, because using the r600 triple for these GPUs will be deprecated in
the future.

8082990487 R600: Error on initializer for LDS.
Also give a proper error for other address spaces.

8eaed0f63d R600/SI: Change all instruction assembly names to lowercase.
This matches the format produced by the AMD proprietary driver.

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.

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.
