Package global data in COMDAT sections for optimization.
According to the docs, this can significantly reduce the
size of the resulting binary executable.
I've tested build Qt with /Gw locally with and without
LTCG, the result shows /Gw can reduce the binary size
indeed, but not "significantly". The result also reveals
that exes can benefit much more from /Gw than dlls.
The result can be seen from the QTBUG-98894 bug report.

Add some scaffolding to prevent us from running into BC issues due to
the underspecified nature of std::aligned_storage.
Qt 5.15 uses a union { char[], double, qint64 } instead of
std::aligned_storage, so doesn't need the fix.

We were clipping the source rect to the image, both pre and post
scrolling, but did not apply the same logic to the target position.
By computing the target position based on the already clipped source
rect we ensure that the target position is also correct.
This was causing valgrind warnings on Linux, and crashes on Windows,
when trying to test the lower level QBackingStore::scroll() function.
The reason we were not seeing this in practice was that QWidget does
its own sanitation and clipping of the arguments before passing them
on.
As a drive-by, fix the access of image to use constBits instead of a
manual cast, and rename variables to better reflect their use.

Add an assert, because if the range isn't valid, we run into UB in the
