Look beyond SSE2 for Paeth

You can break this CL down into three steps.  Steps 2 and 3 depend on 1.

    Step 1: go to a 16-bit impl.  Speed ~unaffected.
    Step 2: use SSSE3 16-bit abs.  ~20% speedup to Paeth.
    Step 3: use SSE4.1 blendv, total ~25% speedup to Paeth.

Overall this can improve PNG decoding by around 8% end-to-end.

I would feel most comfortable landing this only after we have a bot exercising the SSE4.1 code, either by moving this stuff behind a function pointer (simulating Chrome/Clank) or by adding a builder with at least SSE4.1 at compile time (simulating an Android system build).  We've got plenty of bots building with SSSE3 at compile time to test that path.

A variety of SkPngCodec clean-ups

(1) Remove #ifdefs that extend support to > 1.2.
Using nullptr everywhere should work on all versions.

(2) Use png_get_valid(tRNS) to check for transparency
It does the same thing we were doing previously in less
work.

(3) Remove image size check
Clients allocate their own memory, and they have the option
to perform scaled and partial decodes.  So we don't need
to arbitrarily fail on large images.

(4) Remove FIXME for subsitute trans color
libpng is already doing this for us.

(5) Remove #ifdef PNG_READ_PACK_SUPPORTED
We don't have a fallback, so we'll fail to compile if this
isn't supported.

Replace the id<-->key hashmap in SkImageFilter by a SkTArray

In the current implementation, SkImageFilter::Cache maintains a hash map
that maps SkImageFilter's uniqueID to an array of keys, and its purpose
is to remove the values in Cache that are associated with this array of
keys that are indexed by uniqueID. However, maintaining this hash map
causes perf regression to smoothness.tough_filters_cases.

This CL removes the id<-->key hashmap. Instead, we maintain an array of
keys in SkImageFilter. Whenever there is a new key, we push it into the
array. In ~SkImageFilter(), we call Cache::purgeByKeys to remove all the
values that are associated with the keys that are maintained by SkImageFilter.

Treat bad values passed to --images as a fatal error

If an option is passed to --images that is either a non-existent path or
a folder with no images matching the supported types, assume this is
an error and exit, so they can supply a valid path instead.

Share code between DM and nanobench in SkCommonFlags.

nanobench now behaves more like DM - it will check a directory for
images that match the supported extensions.

Only consider image paths ending in RAW suffixes as images if
SK_CODE_DECODES_RAW is defined. This prevents us from seeing failure
to decode errors on platforms that cannot decode it.

Image filters: Make a recursive, forward-mapping bounds
traversal which respects the CropRect. This is useful when
you want the device-space bounds of a primitive after
filtering. (This may also eventually subsume
computeFastBounds()).

This CL generalizes filterBounds() and onFilterBounds() to
take a mapping direction. It also makes filterBounds()
responsible for calling onFilterNodeBounds() and applying
the crop rect, simplifying onFilterBounds().

sketch hooking into PNG_FILTER_OPTIMIZATIONS

Local timing says this 4-byte Paeth function takes about 0.3x the time the serial libpng code does, dropping from ~10 cycles per byte to ~2.9.

bpp=4 is mainly an easy demo.  This approach can work for any bpp up to 16, 1 pixel at a time, at roughly the same cost per pixel.  Doing more than 1 pixel at a time is a tricky math problem I have yet to attempt to solve.

Everything here can be trivially downgraded to MMX, supporting bpp up to 8.  It seems to be a little slower (~3.5 cycles per byte), but it would make the code compatible with every x86 that can still power on.

I've tried four approaches:
  - this way;
  - doing things naively in 16-bit;
  - a 16-bit version that requires division by 3 (i.e. mulhi_epu16(..., 0x5580) );
  - a mostly 8-bit version of the same.

They're all fine, but this one is consistently the fastest I've measured.
I'd be happy to settle on the naive 16-bit version too, which would have a very clear implementation that's only minorly slower than this version.  The other two are way more complicated, and would require us to draw some serious ASCII diagrams to explain.

I have learned that the .skp serialization tests (serialize-8888) have a nice side effect of testing the correctness of these filters!

(Since writing the description above, I've bumped things up to {Paeth,Sub,Avg} x { 3 bpp, 4 bpp }.)

Image filters: fix srcOffset handling in asFragmentProcessor() path.

Filters such as SkMatrixConvolutionImageFilter which use the
asFragmentProcessor() path were not correctly handling srcOffset.
It is correctly applied to the bounds, but the srcRect and dstRect
were computed from the pre-offset bounds.

The fix is to move them to just above where they're used in drawing.

Note: this change adds a new test case to the imagefiltersgraph GM,
so it will have to be rebaselined post-landing.
