9ff378b01b Rewrite memset benches, then use results to add a small-N optimization.
The benches for N <= 10 get around 2x faster on my N7 and N9.  I believe this
is because of the reduced function-call-then-function-pointer-call overhead on
the N7, and additionally because it seems autovectorization beats our NEON code
for small N on the N9.

My desktop is unchanged, though that's probably because N=10 lies well within a
region where memset's performance is essentially constant: N=100 takes only
about 2x as long as N=1 and N=10, which perform nearly identically.

f0ea77a363 SSE2 implementation of memcpy32
With SSE2 version memcpy32, S32_Opaque_BlitRow32() in SkBlitRow_D32.cpp
has about 30% performance improvement. Here are the data on desktop
i7-3770.

608d63735f Choose memset procs once.
TSAN shows us racing on the function pointers.  Might as well fix it.

e61a86cfa0 Guard against most unintentionally ephemeral SkAutoFoo instantiations.
I think I applied the trick everywhere possible.  Limitations:
    - can't be used with templated classes
    - all constructors and destructors must be defined inline

A couple of the SkAutoFoo were unused in Skia, Chromium, and Android, so I
deleted them.  This change caught the same bugs Cary found in SkPath, plus one
more in SampleApp.
