Currently MachineMemOperand relies on MachinePointerInfo to represent its
address space. MachinePointerInfo assumes address space of Stack and
FixedStack kind is 0, which is not true for certain targets (e.g. amdgcn).

This patch let MachinePointerInfo assumes alloca address space of data layout
for Stack and FixedStack kind, therefore MachineMemOperand returns correct
address space for temporary SDNode generated during LLVM codegen.

This fixes failures of OpenCL conformance test basic/vload_private on target amdgcn---amdgizcl.
