MCSymbolizer::tryAddingSymbolicOperand() overloaded the Size parameter to specify either the instruction size or the operand size depending on the architecture. However, for proper symbolic disassembly on X86, we need to know both sizes, as an instruction can have two operands, and the instruction size cannot be reliably calculated based on the operand offset and its size. Hence, split Size into OpSize and InstSize. For X86, the new interface allows to fix a couple of issues: * Correctly adjust the value of PC-relative operands. * Set operand size to zero when the operand is specified implicitly.
