    includes/Stg.h: remove unused 'wcStore' inline
    
    Summary:
    Commit reverts never used addition in cbd29e0a23bb8e15033edae123d6c8fbe9740c97
    
    I think it might make sense to take advantage of TSO/RMO/PSO models
    tome day. But it's highly architecture/model-dependent thus it better
    be implemented in per-arch Native CodeGen.

    Test Plan: build-tested on UNREG-amd64
