[Qt-creator] Building master with MSVC12 and Qt 5.5 fails

[Jochen Becher]

Hi,

I tried to build current master with MSVC12 and Qt 5.5. It failed
because Q_COMPILER_INITIALIZER_LISTS is not defined (needed to compile
some classes which use QVector<> constructor with initializer lists).

Is this a bug in Qt 5.5 (MSVC12 does support initializer lists due to
Microsoft's documentation) or should QtCreator not use initializer
lists yet?

Regards, Jochen
