Test for SSE2 at run-time on Windows
To run on ancient CPUs, we compile for Windows with -arch:SSE since
8bd6bf93b7711a7ac7c5cbd7c3bb980481570ebd (August 2014). Thus
_M_IX86_FP gets defined as 1. This meant that LO_SSE2_AVAILABLE did
not get defined, and that we hardcoded tools::cpuid::hasSSE2() as
always returning false. That was hardly the intent.
