0730ff4c4a added a comment for future: some memory operations must be done atomically 
these are include LOCKed RMW of course and also a lot of others
in the future it will be very hard to find all the cases that must be atomic so better to start marking them already now
try to mark every RMW case for atomicity requirements
no code changes, only comments

code refactor towards fixing issue #2 (#112) 
next step new methods for VEXPANDPS_MASK_VpsWpsR and
VEXPANDPD_MASK_VpdWpdR with mask and memory operand will be introduced
with fault suppression support
legacy load methods aren't good because the loads here actually read
POPCNT(mask) elements from memory src
