Tom Stellard 49f8bfdcb7 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.

Matt Arsenault fb13b22d9a R600/SI: Change mubuf offsets to print as decimal
This matches SC's behavior.

Matt Arsenault cc8d3b8774 R600: Error on initializer for LDS.
Also give a proper error for other address spaces.

Tom Stellard 326d6ece94 R600/SI: Change all instruction assembly names to lowercase.
This matches the format produced by the AMD proprietary driver.

Matt Arsenault 1a74aff846 R600/SI: Also try to use 0 base for misaligned 8-byte DS loads.

Matt Arsenault e775f5fe76 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.

Matt Arsenault 61cc9083d0 R600/SI: Change how DS offsets are printed
Match SC by using offset/offset0/offset1 and printing
in decimal.

Matt Arsenault 410332860d 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.
