instruction semantics

[aquynh]

you can take advantage of some advanced API of Capstone to check the semantics of instructions.
since instructions are classified in groups, you can do in Python:

• check if an instruction is a RETURN instruction with:
  if i.group(CS_GRP_RET):
  ....
• check if an instruction is a kind of JUMP instruction with:
  if i.group(CS_GRP_JUMP):
  ....

there are few more type of groups such as CS_GRP_CALL, CS_GRP_IRET, etc.
see __init__.py & x86_const.py for more info.

I didn't know this, thank you. I will add it.

if you find anything wrong on the group information (such as an instruction belongs to a wrong group, or group is totally missing), please report.

thanks.
