Use xed_decoded_inst_operand_action() for CLI/examples

[andreas-abel]

When using the XED command interface (in verbose mode) or the xed-ex4 example with an instruction like "vaddpd zmm0 {k1}, zmm1, zmm2", the first operand is printed as

0 REG0/W/ZF64/EXPLICIT/NT_LOOKUP_FN/ZMM_R3

It would be helpful if the W could be changed to RCW, which is the output of the xed_decoded_inst_operand_action() function for this example.

This was done somewhat intentionally. There is a chart in xed_decoded_inst_operand_action() that explains what is going on (mostly). The operands' action is mediated by the mask register used. The debug message is printing essentially some internal stuff, which is normally directly usable, but in this case it requires further interpretation.
