MSVC: Fix use of POPCNT instruction without CPU check
The __popcnt family of intrinsics with MSVC generates directly the
POPCNT instruction and are documented to do so:
https://msdn.microsoft.com/en-us/library/bb385231.aspx
So we can't use __popcnt unless the target processor supports it.
[ChangeLog][Windows] Fixed a bug that caused applications to crash with
"Illegal instruction" faults when compiled with Visual Studio and run on
some older processors.
Task-number: QTBUG-58446
