[Development] git 5.8.0 build failure with vs 2017 rc error C3615: constexpr function 'QAlgorithmsPrivate::qt_builtin_ctz' cannot result in a constant exp ression

[Friedemann Kleint]

Hi,

 >My try to build qt 5.8.0 from git using vs2017 rc (CL 19.10.24629) 
failed already when building configure. (commit 
2c27ccd1c9a821edd071cae6336ecb2066ce2ab7)
 >the qt 5.8 beta did work. Using  CL 19.00.24213.1 (vs2015 upd3 + kb) 
also works.
 >does anyone have the same problem? Probably constexpr was activated 
for this compiler but not tested.
