Most of the CPU time was spending in fetching pixel values instead of
calculating the bilinear sample. The access to vectors unions turns
out to be very slow, and should be avoided. This patch removes the
uses of vector,int array union in the bilinear sampling for SSE2.

If a cosmetic polyline contained a 1-pixel segment, the next segment
would be drawn with wrong starting point.
The original fix for QTBUG-26156 had some unwanted side effects
(QTBUG-31579 and now QTBUG-42398). It tried to skip start-point update
if stroke() did not actually draw anything (because the segment was
too small). However, to determine that, it tested for a change in
lastPixel. But that was not failsafe; in some cases (1-pixel segment),
lastPixel could be unchanged even though the segment had been
drawn. With this change, we instead test directly whether stroke()
skipped the segment or not.

Following up on using GCC's autovectorizing for faster SSE4.1
premultiply, this patch adds specialized autovectorized versions
of premultiply for AVX2, giving another almost doubling in speed.
To make the speed up for AVX2 and also SSE4_1 available to non-GCC
compilers, the target-specific methods have been moved to separate
files.

which did not only fix undefined (signed left-shift), but also
implementation-defined (signed right-shift) behavior. It turned out
that code depends on a particular implementation behavior (logical
instead of arithmetic right-shift), and needs to be fixed first.
