SkPx has triggered a bunch of small (2-9%) regressions on NEON devices.

For oval paths, GrPath ignores the point order and only uses the bounds
when building its key. This is problematic because
1) point order is important when dashing
2) GrStencilAndCoverPathRenderer asserts that the lookup SkPath is equal
to the cached SkPath - which is not the case for ovals with different
directions/different point order.
With this CL we no longer use the reduced oval key when dashing, and
instead fall through to the more general path cases. The assert is
adjusted to accommodate "equivalent" ovals (when not dashing).
Also re-enabled & updated the GpuDrawPath unit test (disabled in
https://codereview.chromium.org/1456463003/, presumably due to the use
of uninitialized SkRects).

Need to reland with #define guards for tiny layout test changes. (Yikes!)

DebugWriteToStderr isn't defined for Android. I'm not sure if I just didn't test compiling for Android or if this is due to a change in the base library.
BUG=skia:
No public API changes.

Move createFragmentProcessor to GrTextureProducer base class.
Make non-tiled sw-bitmap draws go through drawTextureProducer.

DIVBITS_ITER was shifting bits up into the sign bit, which is a no-no.
This turns numer into a uint32_t to make those defined, and adds a few notes.
x >= 0 is always true for unsigned x, so we needed a few small logic refactors.

The general SkImage features seem to be tested in
ImageTest instead of SurfaceTest.
Helps in reviewing further reformatting of SurfaceTest.

_mm_mulhi_epu16 makes the (...*257)>>16 part simple.
This seems to speed up every transfermode that uses div255(),
in the 7-25% range.
It even appears to obviate the need for approxMulDiv255() on SSE.
I'm not sure about NEON yet, so I'll keep approxMulDiv255() for now.
Should be no pixels change:

- extract alpha from a pixel: 5 1-cycle ops to 4 1-cycle ops
- load alphas: drop 4 unnecessary ops
Should be no pixel diffs.

Extend the SkPath API to allow specifying the contour starting point.
This will allow removing the explicit cubic code from Blink/Path.

- streamline the testing down to just byte multiplies
(that's always where the blend algorithms vary)
- add another approximate multiply (x*y+255)>>8
- add another variant of the perfect multiply, ((x*y+128)*257)>>16
I've realized ((x*y+128)*257)>>16 might be just as fast in SSE/NEON
as our current (x*y+x)>>8 approximation. Good to be testing it here.

testcase7.bmp leaves uninitialized memory.
Also remove "subset" dm flags. The "subset" test no longer
exists.
