Prevent crash in drawhelper code when the cpu has MMXEXT but no SSE.
We can't use the qdrawhelper_sse.cpp or qdrawhelper_sse3dnow.cpp when
SSE is not run-time detected, as those are compiled with -msse and
MMXEXT is just a subset of SSE. The compiler might choose to use an
instruction not in the subset, causing a crash at run-time.
