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 dc10307524 R600/SI: Only form min/max with 1 use. 
If the condition is used for something else, this increases
the number of instructions.
