Describe the feature you'd like
@Rot127 and I have discussed this before, but I can't see an issue for this and wanted to make sure it wasn't lost!

Essentially, when disassembling with real detail (i.e. using the -r flag for cstool, or CS_OPT_DETAIL_REAL) the mnemonic and operand string are not updated to match the real detail - they are still that of the alias.

I think it would add clarity to also revert the opcode mnemonic and operand string (perhaps alongside the alias) so that one can align each Capstone operand "object" with the diassembled string.
