Fix occasional wrong normal for curves with minimum width.
...
This caused a couple of fireflies in koro_final.blend. The wrong normal would
cause the shading point to be set as backfacing, which triggered another bug
with hair BSDFs on the backface of hair curves. That one is not fixed yet but
there's a comment in the code about it now.

Cycles: avoid 1.0f/(1.0f/x) divisions, which msvc (only) can't optimize.
...
This makes bmw scene in msvc 12 builds 6% faster.
It also gives a minor speedup for SSE hair in all compilers.
