Manually vectorizing is significantly faster because we can optimize
for common cases like long stretches of opaque or transparent pixels.
This is both smaller and faster than the auto-vectorized version, it is
also much faster than the autovectorized version for AVX2 which then can
be removed.

The alpha channel of an RGB32 image was not properly ignored when doing
blending with partial opacity.
Now the alpha value is properly ignored, which is both more correct
and faster. This also makes SSE2 and AVX2 implementations match NEON
which was already doing the right thing (though had dead code for
doing it wrong).

The pixman drawhelpers are implemented using GAS syntax, which the
Clang assembler doesn't handle, nor do they work on 64-bit ARM, so
we disable them selectively. They are only used for 16-bit surfaces
anyways, so it not a big deal on iOS.

The __ARM_NEON is the standard define for NEON instructions support
__ARM_NEON__ is only legacy, and specifically not defined in

The NEON assembler files doesn't build with AArch64, so the NEON

The calculation of the width/height required for the
scaling algorithm was prone to floating point rounding
issues, where the lower value got rounded down, the higher
one rounded up. This could lead to a situation where we
iterated over one more line/pixel in the line than we have
in the source image.
Correct this by passing the dimension of the source image into
the function and bounds checking the values before iterating.

The QT_HAVE_xxx macros are replaced with QT_COMPILER_SUPPORTS_xxx.
They indicate that the compiler supports those intrinsics, but not
necessarily that they can be used right now.
ICC and MSVC allow one to use the intrinsics anywhere, but for Qt all
uses of the intrinsics are either in specially-built files, protected
by runtime checks, or they are unconditional (qstring.cpp). So we only
use the intrinsics when the compiler was instructed to generate code
for that instruction set anyway.
