The commit 90642dd2b6b14c39cc6178f1161331895809b342 introduce a fast
way to convert from RGB888 to RGB32 with SSSE3.
This patch uses that function to do the color conversion when decoding
jpeg images.
The #defines for the SIMD extension have been moved to the common code
in order to be able to compile the jpeg handler directly in QtGui or
as a plugin.

Converting from RGB encoded on 24bits to RGB encoded on 32 bits is
quite inefficient.
This type of conversion is common for some image format.
The patch implement the conversion with SSSE3. This reduce by 3 the
number of instructions, pushing the bottleneck to memory bandwidth.
On Atom N450, the new benchmark is 40% faster for scanlines of
2000 pixels, 30% faster for scanlines of 32 pixels, and 15% slower
for small images (3 and 8px).
