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.

Craig Topper 589ceee7f4 Minor cleanup to all the switches after MatchInstructionImpl in all the AsmParsers. 
Make sure they all have llvm_unreachable on the default path out of the switch. Remove unnecessary "default: break". Remove a 'return' after unreachable. Fix some indentation.

Tom Stellard 9d7ddd516e R600/SI: Start implementing an assembler 
This was done using the Sparc and PowerPC AsmParsers as guides.  So far it
is very simple and only supports sopp instructions.
