Remove Sk prefix from some bench classes.
...
This idea came while commenting on
https://codereview.chromium.org/343583005/
Since SkBenchmark, SkBenchLogger and SkGMBench are not part of the Skia library,
they should not have the Sk prefix.

Add sk_memcpy32 to Memcpy bench.
...
The bench predates the implementation in SkUtils, but now that we've got it of course we want to measure our actual implementation.

Fix memcpy32_sse2_unalign.
...
The whole point of mempcy32_sse2_unalign is that we didn't align dst128
and src128. So it's not safe at all to cast them back to dst and src.
That tells the compiler that dst/src are 128-bit aligned, and then it
autovectorizes the cleanup while-loop using that (false) knowledge with
aligned SSE instructions.
This leads to crashes on memcpy32_sse2_unalign_10, which is small enough
that we actually get non-16-byte aligned memory. The larger size
benches could be crashing too, but they're big enough allocations that
they're probably always 16-byte aligned anyway.

Add Memcpy32 bench.
...
This compares 32-bit copies using memcpy, autovectorization, and when SSE2 is
available, aligned and unaligned SSE2.
Running this on my desktop (Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz), I see
all four perform essentially the same, except Clang's autovectorization looks
a little better than GCC's. memcpy is calling libc 2.19's __memcpy_sse2_unaligned.
