Description
Displaying a SpriteSequence crashes the app on iOS, but only if QtQuick.Particles 2.0 is imported.
This is a regression as the problem definitely did not occur Qt 5.4.
The crash seems to happen when the QML import scanner imports the library libparticlesplugin.prl (full path: /5.9/ios/qml/QtQuick/Particles.2/libparticlesplugin.prl).
Crash happens in QSGBatchRenderer::ShaderManager::prepareMaterial (qsgbatchrenderer.cpp line 150).

Minimal example:
- Removing the line "import QtQuick.Particles" makes it work without crashing
- Image used is Qt logo from http://brand.qt.io/downloads/ (though it crashes with any image)
