Disable SSE optimizations on i386/amd64 for SlowBcopy.
It is supposed to be slow, and when such instructions are used to copy
data from/to mapped video memory, some hypervisors (e.g. KVM,
Microsoft Hyper-V) can generate SIGILL or SIGBUS exceptions, causing
Xorg to crash.
Bug report to OpenBSD by Max Parmer, fix from FreeBSD (Dimitry Andric)
