We only need to clip a temporary x to ensure that we don't blit
beyond clip. Storing such clipped x is problematic because it
may make our edges unsorted.

This basically unrolls all loops, handling twice as many pixels in a
stride. We now pass around 4 native registers instead of just 2.
I've temporarily disabled AVX2 mask loads and stores. It shouldn't be
hard to turn them back on, but I'd want to test on AVX2 hardware first.

This new source acts like other sources (GMs, SKPs) for benchmarks. It
times multiple samples (controlled by samples=N, default 20), and each
of those samples uses the same strategy as monobench, growing loops
exponentially until it runs for at least 10ms.
When done it prints the fastest and the two slowest samples. In
practice the 100th percentile sample is very different from the
next slowest due to caching, and the fastest is always interesting.
Because these benchmarks run in whatever execution engine ok has
selected, on non-Windows platforms you have some real control over the
interaction between benchmarks. In its default "fork" mode each
benchmark runs independently in its own process, so the 100th
percentiles really stand out. The other modes "thread" and "serial"
work as you'd expect too.
Here's an example where you can see how the different interactions work:
out/ok bench:samples=100 8888 filter:search=text_16_AA fork
[text_16_AA_WT] 2.32µs @0 6.23µs @99 24.3ms @100
[text_16_AA_FF] 2.41µs @0 5.7µs @99 23.3ms @100
[text_16_AA_88] 2.55µs @0 5.6µs @99 24.8ms @100
[text_16_AA_BK] 1.97µs @0 5.44µs @99 23.2ms @100
out/ok bench:samples=100 8888 filter:search=text_16_AA thread
[text_16_AA_FF] 2.45µs @0 23.5µs @99 24.8ms @100
[text_16_AA_WT] 2.52µs @0 17.8µs @99 24.7ms @100
[text_16_AA_88] 2.55µs @0 19.7µs @99 25.1ms @100
[text_16_AA_BK] 1.8µs @0 14.7µs @99 25.1ms @100
out/ok bench:samples=100 8888 filter:search=text_16_AA serial
[text_16_AA_88] 2.35µs @0 3.53µs @99 16.7ms @100
[text_16_AA_FF] 2.09µs @0 2.73µs @99 2.91µs @100
[text_16_AA_BK] 1.75µs @0 2.46µs @99 2.65µs @100
[text_16_AA_WT] 2.1µs @0 3.16µs @99 3.17µs @100
In the first "fork" case all runs are independent and have roughly
the same profile. "thread" looks similar except you can see them
contending at the 99th percentile. In "serial", the first bench
warms up the rest, so their 100th percentiles are all much faster.

As a part of serializing SkPaths, I want to be able to know (without
asserting) whether or not a path is valid so that I can discard
potentially malicious deserialized paths.
Currently, SkPath(Ref) both just have asserting validation functions
which can't be used externally. This patch adds accessors that don't
assert.

These symbols were resolving, but weren't really connected to systrace
on Android. Using the macros/functions allows this to work correctly.
This change doesn't actually cause anything to happen in framework
builds - that still requires installing an instance of SkATrace, but
now doing so will route all of Skia's TRACE_EVENT macros to systrace.

1. Always inline (Clang previously ignored inline and got 25% slower)
2. SIMD everywhere other than x86 gcc:
non-SIMD is only faster in my desktop with gcc;
with Clang on my desktop, SIMD is 50% faster than non-SIMD.
3. Allocate 4x memory instead of 2x when running out of space:
on old Android devices with Linux kernel 3.10 (e.g., Nexus 6P, 5X),
the alloc/memcpy will triger a major bottleneck in kernel (30% of
the running time). Such bottleneck goes away (the kernel is no
longer doing stupid things during alloc/memcpy) in Linux kernel
3.18 (e.g., Pixel), and that's why DAA is much faster on Pixel than
on Nexus 6P.
I think maybe I should adopt SkRasterPipeline for device-specific
optimizations.
