Merge remote-tracking branch 'origin/5.7' into 5.8

cf53aa21bf0f8fbd13c0ce2d33ddf7bc63d0d76a and 3aaa5d6b32130d3eeac872a59a5a44bfb20dfd4a
were reverted because of reconstruction in 5.7.

defineTest(qtConfTest_checkCompiler) in configure.pri is smart
enough to cover the case in a9474d1260a8c8cc9eae14f2984098919d9684e5.

DirectWrite: Fix advances being scaled to 0

Since 131eee5cd, the stretch of a font can be 0, meaning
"whatever the font provides". In combination with ec7fee96,
this would cause advances in the DirectWrite engine to be scaled to
0, causing the QRawFont test to fail.
