  -----------
  [AMDGPU] Move kernarg preload logic to separate pass

Moves kernarg preload logic to its own module pass. Cloned function
declarations are removed when preloading hidden arguments. The inreg
attribute is now added in this pass instead of AMDGPUAttributor. The
rest of the logic is copied from AMDGPULowerKernelArguments which now
only check whether an arguments is marked inreg to avoid replacing
direct uses of preloaded arguments. This change requires test updates to
remove inreg from lit tests with kernels that don't actually want
preloading.
