A new target feature new-addr is added. When it is on, AMDGPU uses new address space mapping where generic address space is 0 and private address space is 5. The data layout is also changed correspondingly. By default this feature is off.

This is the beginning of an upstreaming effort for changing address space mapping of AMDGPU target. Sema/CodeGen changes to make OpenCL/C++ working with the new address space mapping will follow.
