[PATCH] D64259: AMDGPU: Make AMDGPUPerfHintAnalysis an SCC pass

Add a string attribute instead of directly setting
MachineFunctionInfo. This avoids trying to get the analysis in the
MachineFunctionInfo in a way that doesn't work with the new pass
manager.

      

This will also avoid re-visiting the call graph for every single
function.
