Thiago Macieira c3a4ec5d0b SIMD: Add a haswell sub-architecture selection to our support 
As the comment says, Haswell is a nice divider and is a good
optimization target.

I'm using -march=core-avx2 instead of -march=haswell because the latter
form was only added to GCC 4.9 but we still support 4.7 and that has
support for AVX2.

This commit changes the AVX2-optimized code in QtGui to Haswell-
optimized instead. That means, for example, that qdrawhelper_avx2.cpp
can now use the FMA instructions.
