Summary: This represents the adjustment applied to the implicit 'this' parameter in the prologue of a virtual method in the MS C++ ABI. The adjustment is always zero unless multiple inheritance is involved. This increases the size of DISubprogram by 8 bytes, unfortunately. The adjustment really is a signed 32-bit integer. If this size increase is too much, we could probably win it back by splitting out a subclass with info specific to virtual methods (virtuality, vindex, thisadjustment, containingType).
