commit fbd28e2c6b5f1302cd2d36d79149e3b0a9f01d84

    Allow CmmLabelDiffOff with different widths
    
    Summary:
    This change makes it possible to generate a static 32-bit relative label
    offset on x86_64. Currently we can only generate word-sized label
    offsets.
    
    This will be used in D4634 to shrink info tables.  See D4632 for more
    details.
    
    Test Plan: See D4632
