Summary

Added disassembly support for the following shifted register instructions:

adds
subs
sub
neg
negs
cmp
cmn

According to documentation Arm64 original istructions are always
preferred disassembly, hence for:

cmn (shifted register) we use adds
cmp and negs (sifted register) we use subs
neg (shifted register) we use sub
