b069582d16 Add regression test for oss-fuzz:32156.
The fuzzer found that it could overflow an int via a properly-crafted
constant-fold expression, leading to a UBSAN error. Constant-fold
expressions now guard against overflow (http://review.skia.org/413138)
and UBSAN is no longer triggered.

expression containing a uniform). The uniform always has the
same name. Bake these simplifications in, which also shrinks

f2b08cc9c8 Fix SPIR-V code generation of dead return statements.
If we encounter code like `return 1; return 2;` we need to synthesize a
label, even though the second return statement isn't actually reachable.
This is harmless and satisfies the SPIR-V validator.

Ideally we'd eliminate the dead code entirely, but this case is rare and
isn't likely to cause any problems as-is.

4e9d5e2bdf Use Wang's formula for quadratic and cubic point counts
- most of the small diffs are because I moved GrWangsFormula.h out
   of the tessellate/ directory and into the geometry/ directory since
   it's more general than HW tessellation.

The previous implementation was based on the heuristic that the distance
from the true curve to the line segment would be divided by 4 every time
the curve was recursively subdivided. This was a reasonable
approximation if the curve had balanced curvature on both sides of the
split. However, in the case of the new GM's curve, the left half was
already very linear and the right half had much higher curves.

This lead to the approximation reporting fewer points than required.
Theoretically, those few points that weren't utilized by the left half
of the curve could have been made available to the right half, but the
implementation of that would be tricky.

Instead, it now uses Wang's formula to compute the number of points.
Since recursive subdivision leads to linearly spaced samples assuming it
can't stop early, this point count represents a valid upper bound on
what's needed. It also then ensures both left and right halves of a
curve have the point counts they might need w/o updating the
generation implementations. However, since the recursive point
generation exits once each section has reached the error tolerance, in
scenarios where the prior approximation was reasonable, we'll end up
using fewer points than reported by Wang's. Hopefully that means there
is negligible performance regression since we won't be increasing
vertex counts by that much (except where needed for correctness).

371f6e18e5 Refactored SkSL function creation and error handling
This breaks up the giant IRGenerator::convertFunction method into more-
manageable chunks, moves the functionality into FunctionDeclaration,
and funnels the DSL through it so it receives the same error checking.

adadb95a9f Better first-class shader & color filter support in runtime effects
This does a few things, because they're all intertwined:

1) SkRuntimeEffect's API now includes details about children (which Skia
   stage was declared, not just the name). The factories verify that the
   declared types in the SkSL match up with the C++ types being passed.
   Today, we still only support adding children of the same type, so the
   checks are simple. Once we allow mixing types, we'll be testing the
   declared type against the actual C++ type supplied for each slot.
2) Adds sample variants that supply the input color to the child. This
   is now the only way to invoke a colorFilter child. Internally, we
   support passing a color when invoking a child shader, but I'm not
   exposing that. It's not clearly part of the semantics of the Skia
   pipeline, and is almost never useful. It also exposes users to
   several inconsistencies (skbug.com/11942).
3) Because of #2, it's possible that we can't compute a reusable program
   to filter individual colors. In that case, we don't set the constant
   output for constant input optimization, and filterColor4f falls back
   to the slower base-class implementation.

6c41bf55b7 Create mini-skia for RenderEngine
Bug: b/167743764

Android's RenderEngine is now using Skia, but it doesn't need all the
pieces of Skia used by HWUI. Make a smaller version of Skia that
excludes many of those pieces, in particular where they bring in other
dependencies:
- codecs
- text
- pdf
- xml

Add a new cc_defaults to be shared by the new libskia_mini and libskia.

Manually insert fexceptions into libskia, since it is only needed by
SkRawCodec (not needed by mini).

Add a new SkUserConfig for mini, so it can exclude defines like
SK_CODEC_DECODES_PNG.

Continue to link in libpng (and libz, which it depends on) and build
SkPngEncoder, so that SKP captures can include compressed image files.

Switching to the mini-skia reduces the size of surfaceflinger from 7.4M
to 6.0M.
