◆ gatherResourceInfo()

AMDGPUResourceUsageAnalysis gathers resource usage on a per-function granularity.

However, some resource info has to be assigned the call transitive maximum or accumulative. For example, if A calls B and B's VGPR usage exceeds A's, A should be assigned B's VGPR usage. Furthermore, functions with indirect calls should be assigned the module level maximum.
