Export optimized premultiply and unpremultiply methods
This patch optimizes the unpremultiply method further by using a
lookup table to avoid any divisions at all.
The opportunity is taken to export both premultiply and unpremultiply
since they are commonly used methods relevant to the exported QRgb type
that can be both premultiplied and unpremultipled ARGB.
[ChangeLog][QtGui][QColor] Exported highly optimized methods for
premultiply and unpremultiply of QRgb values.
