* i386-dis.c (stack_v_mode): Renamed from branch_v_mode.
(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.
