  -----------
  [llvm-calc-occupancy] Add an AMDGPU occupancy calculator tool (#208727)

Add a command-line utility that reports the occupancy (waves/EU) an
AMDGPU kernel would reach for a given workgroup size, VGPR/SGPR usage
and LDS. It reuses the backend's own occupancy math, so the numbers
match the compiler. Includes a lit test and a CommandGuide man page.
