Remove the old code using MMX registers.
There are only 8 MMX registers, each 64-bit wide, and they alias the x87 registers. The access to the MMX register cannot use the new VEX-prefix instructions either. All of the functions being replaced are either present in the qdrawhelper_sse2.cpp and qdrawhelper_ssse3.cpp files, or the plain C++ function in qdrawhelper.cpp is vectorised when compiled with -ftree-vectorize (enabled in -O3), if SSE2 support is enabled. All x86-64 processors have SSE2, so this is a net improvement for 64-bit builds. For 32-bit builds, without further support this will cause the code to use non-vector or x87 instructions, which aren't the best. The solution will come in another commit.
