NEON configure detection and initial blend function implementations.
Adds new NEON configure test and -no-neon configure option. NEON
implementations can also be turned off by setting the QT_NO_NEON
environment variable.
Performance improvements (in frames per second):
- Blending ARGB32 on RGB32/ARGB32, mostly opaque: 71 %
- Blending ARGB32 on RGB32/ARGB32, no opaque pixels: 108 %
- Blending ARGB32 on RGB32/ARGB32, with 0.5 opacity: 158 %
- Blending RGB32 on RGB32/ARGB32, with 0.5 opacity: 189 %
