Adds basic support for 10-bit per color channel formats to QImage
and the XCB plugin. This will make it possible to paint to and from
these formats, but only at 8-bit per color channel accuracy.
This also fixes Qt5 applications on X11 with native 30bit depth.
[ChangeLog][QtGui][QImage] Added support for 10-bit per color channel image formats.

Add detection of MIPS DSPr2 at run-time in qsimd.cpp. This makes it
possible to have generic Qt builds for MIPS that can enable the fast
code paths for processors with the DSP ASE at run-time. Also, this
makes it possible to manually disable them by setting the environment
variable "QT_NO_CPU_FEATURE=dspr2". Last, but not least, functions
requiring DSPr2 are not enabled when running in CPUs with version-1
DSP.

Add a hand-coded MIPS assembler function to convert a stream of rgb888
bytes to an array of 32-bit ARGB values. This is used in QImage for
image conversion, and also in QJpegHandler for decoding JPEG image
scanlines.

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.

The generic converter can easily be modified to work inplace. Such
an inplace converter can ensure we can do direct conversion between
formats of similar pixel depth.
Inplace conversion is currently only used by QPixmaps, but will be used
by ref qualified versions of QImage::convertToFormat in a future patch.

Now the only way to enable Neon support is to change the mkspec.
[ChangeLog][Important Behavior Changes] Qt no longer checks for
support for the Neon FPU on ARM platforms at runtime. Code optimized
for Neon must be enabled unconditionally at compile time by ensuring
the compiler supports Neon. You may need to edit your mkspec for that.

If the compiler supports SSE2, we'll use our SSE2-optimised code
unconditionally. Runtime detection is left for SSSE3 code.
The SSE2 codebase is big and thus a timebomb if an inline function
gets leaked out and run without runtime check. In reality, it's
extremely unlikely people running CPUs without SSE2 support are
running Qt 5 at this moment (they're either too old or too new,
e.g. Intel Quark).
The SSSE3 codebase is a lot more manageable.

Currently if the converter_map does not have an entry for how to
do a direct conversion, the image is first converted to ARGB32 and
then to the final format. In most cases the conversion to ARGB32 is
the generic converter which convert over ARGB32PM, which mean the data
is converted to ARGB32PM then to ARGB32, then to ARBG32PM and then to
final format.
This patch uses the generic converter directly everywhere there isn't
an optimized converter declared and it is valid.

A large part of qimage.cpp is the implementation of the various
conversions methods from one format to another. These methods could all
be moved to a separate file to make qimage.cpp smaller, and possible
later enable more aggressive optimization on the conversions.
