  Log Message:
  -----------
  [AMDGPU] Replace non-kernel function uses of LDS globals by pointers.

The main motivation behind pointer replacement of LDS use within non-kernel
functions is - to *avoid* subsequent LDS lowering pass from directly packing
LDS (assume large LDS) into a struct type which would otherwise cause allocating
huge memory for struct instance within every kernel.
