Previously, we were abundantly cautious about producing premultiplied
colors with RGB > A, when the color-type was normalized fixed-point.
I'm not seeing any evidence that code cares about that. If it does, I
suggest we fix the issue at the API border, or via dedicated pass. In
the common case, this makes Skia less opinionated, which (in general)
makes it more versatile.

An unused child that used its coordinates would triggers asserts in the
GP - we expect that all FPs are sampled/invoked. This generates slightly
sub-optimal code (we compute and interpolate the local coordinates for
that child FP), but it's not likely to happen in real code.

Previously, deeply-nested loops could lead to stack overflow during SkVM
dead-code elimination. The DCE algorithm in SkVM now stores its worklist
on the heap and does not rely on recursion. Since we now enforce an
upper bound on maximum program size within SkSL, this worklist's size
should always be reasonable and bounded.

A lot of the SkVM-related setup was already hooked up in
http://review.skia.org/416916. This CL finishes the job by hooking up
the SkPaint's SkBlender field to SkVM, and adds various checks
throughout Skia's software drawing code that can detect the presence of
an SkBlender.
Since only SkVM knows how to render an SkBlender correctly, we now need
to avoid the legacy blitter and RasterPipeline blitter whenever an
SkBlender is present on the paint. This CL fixes the cases that I've
found so far, while testing rendering with ovals and images. I'm sure
there are more cases lurking; these will be uncovered and dealt with in
future CLs.

Unit tests have been added to verify basic functionality is working as
expected; more thorough drawing tests will be added once the CPU side is
running as well (since we don't want GMs that render differently on CPU

Constant output for constant input is determined automatically from the
SkSL. The other two flags are trickier, so we just let the caller
specify them. This will be a key part of migrating .fp files to runtime
FPs.
Restored the preserves-opaque-input flag for color FPs when the color is
opaque (an optimization that was lost when this was initially converted
to a runtime FP).

FPs are used to represent effects with varying semantics. In particular,
shaders (that generate colors with no real input), and color filters
(that always have a "primary" input color on which they operate).
Even FPs that are not directly tied to a particular SkShader or
SkColorFilter tend to fall into these two categories. GrSkSLFP was
tailored to the shader semantics. It always supported having child FPs,
but these weren't considered "special" in any way - there could be
multiple, and each one could be sampled in whatever way the SkSL wanted.
This CL adds a dedicated "input" FP slot, so that color filters (and FPs
that resemble color filters) can naturally map better. Previously, we
had to inject an additional FP to do composition of the input and the
SkSL. That worked fine - this change is really about cutting down on
allocations and extra CPU work for that extra FP in the tree.

This CL adds a RuntimeEffect option flag which skips over the various
`strictES2Mode` checks sprinkled throughout IR generation.
Runtime Effects still won't allow a lot of ES3 things (the Pipeline
stage will reject unsupported statement types, SkVM doesn't support most
non-ES2 constructs, etc). However, this change will give us the ability
to test many more features involving arrays and structs that previously
were off-limits due to ES2 restrictions, and will shore up some
legitimate gaps in our testing. This is a useful starting point to allow
for improved test coverage.

All clients have been moved to the stage-specific factories. The old
flexible factories are still used internally (for now), but this
prevents any new usage from creeping in accidentally.

As explained, this is *very* conservative. It only works when the child
is sampled from within main, and using a direct reference to the coords
parameter. If that parameter is ever modified (even after being used),
the optimization doesn't happen. For most cases, this is fine.
Reland changes the logic in GrSkSLFP slightly, to avoid turning all
samples into pass-through when a child is sampled with both pass-through
and explicit coordinates.

This is another strange, experimental feature that clutters the
implementation and isn't used by anyone (to my knowledge).

This reuses the work we're already doing to compute the one-at-a-time
program, and lets us share the result across color filter instances
created from the same effect.
When we added caching of the flag to filter creation, pinpoint found a
performance regression. I expect this to resolve that.
