Mai Lavelle 4e9b17da4c Cycles: Speedup by avoiding extra calculations in noise texture when unneeded ...

Noise texture is now faster when the color socket is unused. Potential for
speedup spotted by @nutel.

Some performance results:

                     Render Time Before    After    Difference
Gooseberry benchmark         47:51.34    45:55.57       -4%
Koro                         12:24.92    12:18.46     -0.8%
Simple cube (Color socket)      48.53       48.72     +0.3%
Simple cube (Fac socket)        48.74       32.78    -32.7%
Goethe displacement           1:21.18     1:08.47    -15.6%
Cycles brick displacement     3:02.38     2:16.76    -25.0%
Large displacement scene     23:54.12    20:09.62    -15.6%
