Short live Q_CONSTINIT!
It expands to the first available of
- constinit (C++20)
- [[clang::require_constant_initialization]] (Clang)
- __constinit (GCC >= 10)
Use it around the code (on and near static QBasicAtomic; this patch
makes no attempt to find all statics in qtbase).
[ChangeLog][QtCore][QtGlobal] Added macro Q_CONSTINIT.
Fixes: QTBUG-100484
Change-Id: I11e0363a7acb3464476859d12ec7f94319d82be7
