591e2aa79f bugfix: when CET was not compiled in the emulation behavior of non-CET CPU was altered 
CET 'change' some x86 behavior
For example EPTP[7] become not-reserved and write to it not fail anymore
VMX doesn't check error code for CP exception if CET is enabled
These behaviors these changed even when CET was not compiled in

6aa399e9eb Added x64 configuration for the VS2019 plugins workspace (fixes issue #8). 
Since VS2019 didn't copy all settings from win32, manually editing all files
was necessary (adding OutDir/IntDir stuff).

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
