27c2b09374 Move Sk4px Xfermode code to a header so we can use it twice.
- Once in SkXfermode as usual to pick up compile-time SSE and NEON
  - Once in SkXfermode_arm_neon to pick up run-time NEON

This allows us to start cleaning up SkXfermode_arm_neon as we've done
for SkXfermode_SSE2.  I'm saving this catharsis for a day when I need it.

The Sk4px xfermodes are generally faster than the existing NEON procs,
so this should also have the side effect of a perf win there.

This means our new Plus-AA code works for runtime NEON too.

GrContext draw functions (drawRect, drawRRect,...) fall back to
GrContext::drawPath for complex cases. Mark the argument SkPath
as volatile, since it is.

This makes Plus with AA ~3% slower.  Seems like a good deal.

GMs affected: mixed_xfermodes, the new one.

Still TODO: NEON.  The new GM should show this.

e59e1b22a3 Whitespace change to trigger builds
Two major things have happened:
1. Android bots split between more machines. This caused lots of
   congestion-related failures, leading to...
2. All buildslaves now use a single checkout for all of the builders
   that they run. This should give us far fewer problems when we have
   to re-download SKPs, toolchains, etc.

0edea2c8e7 Make mixed samples contingent on auxiliary extensions
Moves the cap for mixed samples into GrShaderCaps and does not enable
it unless we have support for both dual source blending and
multisample disable.

Creates a dedicated cap for multisample disable.

Reconfigures the mixed samples cap to indicate the collective
capability of three different extensions:

  GL_NV_framebuffer_mixed_samples
  GL_NV_sample_mask_override_coverage
  GL_EXT_raster_multisample

Imports tokens and procedures for GL_EXT_raster_multisample.

b4a797f3aa Move font loading in gm tests and benches out of constructors
Constructing the gm tests and benches causes many calls to font loads.
This is visible as profiling samples in fontconfig and freetype on Linux
for all profiling runs of nanobench. This complicates analysis of
test-cases that are suspected of being slow due to font-related issues.

Move the font loading to GM::onOnceBeforeDraw and Benchmark::onPreDraw.
This way the code is not executed if the testcase does not match the
nanobench --match filter. This way the samples in font-related code are
more easy to identify as legitimate occurances caused by the testcase.

This should not cause differences in timings, because:
* Benchmark::preDraw / onPreDraw is defined to be run outside the timer
* GM::runAsBench is not enabled for any of the modified testcases. Also
  nanobench untimed warmup round should run the onOnceBeforeDraw.
  (and there are other GM::runAsBench gms already doing loading in
   onOnceBeforeDraw).

Changes the behavior:
In TextBench:
Before, the test would report two different gms with the same name if
the color emoji font was not loaded successfully.
After, the test always reports all tests as individual names.

Generally:
The errors from loading fonts now print inbetween each testcase, as
opposed to printing during construction phase. Sample output:

2e172ecd3b Make SkEmptyPicture a singleton.
In my confusion yesterday I accidentally left this as a non-singleton.
The issue in Blink was not related to this being a singleton,
and it should be safe to make it one.

This means recording an empty picture properly costs zero mallocs.

22483d9ca6 Sort build files for consistent link order.
Prior to the introduction of find.py, GMs were liked in the order they
were listed in the gypi file, which was generally alphabetically. This
made it fairly easy to predict where slides would show up in SampleApp
and the order was consistent. This simply sorts the list of files in
find.py to restore the expectation that files should be listed in the
build in alphabetical order.

d8b5771779 Don't fail SkMergeImageFilter if one of the inputs are empty
If one of the inputs to a SkMergeImageFilter was clipped away or
otherwise caused the filterImage(...) invocation for it to return
false, the entire effect would be "failed" and return false --
regardless of if it had produced a result or not.
Instead of returning false directly if filterImage(...) for a source
returned false, consider all the inputs, and then only return false if
all of them do.

9db912c2ac Sketch splitting SkPicture into an interface and SkBigPicture.
Adds small pictures for drawRect(), drawTextBlob(), and drawPath().
These cover about 89% of draw calls from Blink SKPs,
and about 25% of draw calls from our GMs.

SkPicture handles:
  - serialization and deserialization
  - unique IDs

Everything else is left to the subclasses:
  - playback(), cullRect()
  - hasBitmap(), hasText(), suitableForGPU(), etc.
  - LayerInfo / AccelData if applicable.

The time to record a 1-op picture improves a good chunk
(2 mallocs to 1), and the time to record a 0-op picture
greatly improves (2 mallocs to none):

    picture_overhead_draw:   450ns -> 350ns
    picture_overhead_nodraw: 300ns -> 90ns

612f70d5fa handle large conic strokes better
A stroked conic computes the outset quad's control point by
computing the intersection of the quad's endpoints. If the
the denominator used to compute the scale factor for the
control point is small, check to see if the numerator is also
small so that the division stays bounded.

Also clean up error returns and internal function calls to
simplify the code.

Additionally, remove comic max curvature (unimplemented) and call
extrema functions instead to handle cases where the conic is degenerate
or is a line.
