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 %

If the target rectangle had negative width or height and the target
rectangle's border passed through pixel centres,
qt_scale_image_16/32bit() could crash because of incorrect rounding.

We want to force use of qreal where possible. This can lead to better
performance on platforms where qreal -> float (i.e. ARM). To achieve
this we:
1. changed from 'double' to 'qreal', where justified
2. using qreal() to intialize constants, where justified
3. adding helper functions that are overloaded for qreal
like qAtan2(), qAcos(), qFabs() ...
4. defining QT_USE_MATH_H_FLOATS for Symbian platform
In addtion we used opportunity to improve code with some small things
5. converting divisions to multiplications
(i.e. '/ 2.0' -> '* qreal(0.5)')
6. defining new constants (i.e. 'Q_PI / 180.0' -> 'Q_PI180')
7. declaring variables as 'const', where justified

This test works with the native Sun compiler for some reason, and
the problem is an unaligned read of 16 bits, which is a problem
on several other architectures.

In qt_scale_image_16bit() and qt_scale_image_32bit(), when a sample
point was located on the border between two pixels in the source image,
the sample point was rounded up instead of down. If a sample point was
exactly on the bottom or right edge of the source image, the function
would therefore sample a pixel outside the image. Because of how the
target rectangle is rounded, a sample point will never be exactly on
the top or left edge of the source image, so we will not get a similar
problem there.
I extended the lance test pixmap_scaling.qps.

Add SuperH to the ever growing list of architectures which can't
correctly dereference a short* which is not 16-bit aligned. Turning this
into a white-list rather than a black list might make sense at some
point, but as QT_ARCH_I386 isn't defined on windows, the white list
looks even uglier at the moment. :-)

There was an optimized blend function for this case but not an optimized
scale function. Performance increase seems to be in the order of 5x.

case them in the argb32 on argb32 image blend function.

The "optimized" version of this function was actually slower
by quite a bit, so revert it to the old "trivial" code.

There was special code for gcc to run super-fast, but it was
buggy and didn't blend properly. Kill this code for the benefit
of the normal blend function. The performance on an Intel Quad Core 2
was not too different from the bytemul approach.
