(indirEv): Use it. (stackEv): New. (Ob64, Ov64): Rename to Ob, Ov. Delete unused original definitions. (dis386): Document and use new 'V' meta character. Use it for single-byte push/pop opcode forms. Use stackEv for mod-r/m push/pop opcode forms. Correct typo in 'pop ss'. Replace Ob64/Ov64 by Ob/Ov. (putop): 'q' suffix for 'T' and 'U' meta depends on DFLAG. Mark data prefix as used whenever DFLAG was examined. Handle 'V'. (intel_operand_size): Use stack_v_mode. (OP_E): Use stack_v_mode, but handle only the special case of 64-bit mode without operand size override here; fall through to v_mode case otherwise. (OP_REG): Special case rAX_reg ... rDI_reg only when 64-bit mode and no operand size override is present. (OP_J): Use get32s for obtaining the displacement also when rex64 is present.
