a89dd1d1c4 AMDGPU: Rename flat operands to match mubuf 
Use vaddr/vdst for the same purposes.

This also fixes a beg in SIInsertWaits for the
operand check. The stored value operand is currently called
data0 in the single offset case, not data.

759ed7e410 AMDGPU: Cleanup subtarget handling. 
Split AMDGPUSubtarget into amdgcn/r600 specific subclasses.
This removes most of the static_casting of the basic codegen
classes everywhere, and tries to restrict the features
visible on the wrong target.

022a8990dd Move instances of std::function. 
Or replace with llvm::function_ref if it's never stored. NFC intended.

8478bd5765 AMDGPU/SI: Use the hazard recognizer to break SMEM soft clauses 
Summary:
Add support for detecting hazards in SMEM soft clauses, so that we only
break the clauses when necessary, either by adding s_nop or re-ordering
other alu instructions.
