  -----------
  [AMDGPU] GCNRegPressurePrinter pass to print GCNRegPressure values for testing. (#70031)

Using GCNDownwardRPTracker or GCNUpwardRPTracker the pass collects register pressure values for a function and prints these values next to instructions. Output can be used to generate Filecheck rules in mir tests.
