msarett a9e878c836 Optimize color xforms with 2.2 gammas for SSE2 
Because we recognize commonly used gamma tables and
parameters as 2.2f, about 98% of jpegs with color profiles
will pass through this xform (assuming the dst is also
2.2f).  Sample size is 10,322 jpegs.

I won't go crazy with performance numbers because this is
a work in progress, particularly in terms of correctness.

201295.jpg on HP z620
(300x280, most common form of sRGB profile)

Decode Time + QCMS Xform      1.28 ms
QCMS Xform Only               0.495 ms
Decode Time + Skia Opt Xform  1.01 ms
Skia Opt Xform Only           0.235 ms

Decode Time + Xform Speed-up  1.27x
Xform Only Speed-up           2.11x

FWIW, Skia xform time before these optimizations was
41.1 ms.  But we expected that code to be slow.
