- Remove extract... it's not going to have any special impl.
I've left it on skvm::Builder as an inline compound method.
- Add no-op shift short circuits.
- Add immediate ops for bit_{and,or,xor,clear}.
This comes from me noticing that the masks for extract today are always
immediates, and then when I started converting it to be (I32, int shift,
int mask), I realized it might be even better to break it up into its
component pieces. There's no backend that can do extract any better
than shift-then-mask, so might as well leave it that way so we can
dedup, reorder, and specialize those micro ops.
Will follow up soon to get this all JITing again,
and these can-we-JIT test changes will be reverted.

Currently, we treat track matte source layers (tagged with td:1) as single-shot mask triggers:
we apply once to the following layer, then move on.
But track mattes can cascade: a layer with a matte can itself be applied as a track matte for the
following layer.
Also, for matte/masking purposes, only the layer content is being considered (ignoring blend mode
and any masks applied to the matte itself).
To support this, refactor the layer attachment code:
- instead of tracking the presence of a single-shot matte source, always track
previous layer content trees
- instead of triggering matte attachment in the presence of a matte source, trigger based on
the matte *target* property (tt: X)
- log errors on unknown matte modes

This adds a bunch of tests for ops that can all be evaluated directly in
skvm::Builder. You can see the sort of effect this has by looking at
the diffs for SkVMTest.expected... lots of `v3 = sub_f32 v2 v2`
transformed to `v3 = splat 0 (0)` and that sort of thing.
My favorite part is handling many assert_true() calls at compile time!
While the old inter-Op code parallels aren't as clear now, these new
early-out tests kind of work like comments explaining each op. I find
that nice. I found it hard to parse so many uses of the word "splat" so
I did go back to isImm() from isSplat(), and added allImm() to test for
and read several immediates all at once.
Some of this is less C++17 than I'd like. :/

Lots of x86 instructions can take their right hand side argument from
memory directly rather than a register. We can use this to avoid the
need to allocate a register for many constants.
The strategy in this CL is one of several I've been stewing over, the
simplest of those strategies I think. There are some trade offs
particularly on ARM; this naive ARM implementation means we'll load&op
every time, even though the load part of the operation can logically be
hoisted. From here on I'm going to just briefly enumerate a few other
approaches that allow the optimization on x86 and still allow the
immediate splats to hoist on ARM.
1) don't do it on ARM
A very simple approach is to simply not perform this optimization on
ARM. ARM has more vector registers than x86, and so register pressure
is lower there. We're going to end up with splatted constants in
registers anyway, so maybe just let that happen the normal way instead
of some roundabout complicated hack like I'll talk about in 2). The
only downside in my mind is that this approach would make high-level
program descriptions platform dependent, which isn't so bad, but it's
been nice to be able to compare and diff debug dumps.
2) split Op::splat up
The next less-simple approach to this problem could fix this by
splitting splats into two Ops internally, one inner Op::immediate that
guantees at least the constant is in memory and is compatible with
immediate-aware Ops like mul_f32_imm, and an outer Op::constant that
depends on that Op::immediate and further guarantees that constant has
been broadcast into a register to be compatible with non-immediate-aware
ops like div_f32. When building a program, immediate-aware ops would
peek for Op::constants as they do today for Op::splats, but instead of
embedding the immediate themselves, they'd replace their dependency with
the inner Op::immediate.
On x86 these new Ops would work just as advertised, with Op::immediate a
runtime no-op, Op::constant the usual vbroadcastss. On ARM
Op::immediate needs to go all the way and splat out a register to make
the constant compatible with immediate-aware ops, and the Op::constant
becomes a noop now instead. All this comes together to let the
Op::immediate splat hoist up out of the loop while still feeding
Op::mul_f32_imm and co. It's a rather complicated approach to solving
this issue, but I might want to explore it just to see how bad it is.
3) do it inside the x86 JIT
The conceptually best approach is to find a way to do this peepholing
only inside the JIT only on x86, avoiding the need for new
Op::mul_f32_imm and co. ARM and the interpreter don't benefit from this
peephole, so the x86 JIT is the logical owner of this optimization.
Finding a clean way to do this without too much disruption is the least
baked idea I've got here, though I think the most desirable long-term.

Observed AE layer parenting semantics:
* layers are flagged as either 2D or 3D
* camera applies to 3D layers, but not to 2D layers
* parented 3D layers treat their ancestor transform chain as 3D (SkMatrix44)
* parented 2D layers treat their ancestor transform chain as 2D (SkMatrix, ignoring 3D components)
This means that for a given layer, we may need to build two distinct transform chains - depending
on the type of descendant layer being considered.
Furthermore, transforms are animatable and their animators are scoped to a layer controller. Since
we're potentially building two version of the transform node, we need to ensure all animators for
both of them are transferred to controller object (we still want to only instantiate a single layer
controller and render tree to avoid duplication). IOW, all dependent layer transforms need to be
considered before "sealing off" a given layer controller.
In order to avoid a layer dependency/topological sort, we can split off the transform tree
construction into a separate pass. High-level changes:
-- replace existing LayerAttachContext with CompositionBuilder
(holds LayerBuilders and other Composition-wide state)
-- replace LayerRec with LayerBuilder
(holds Layer-wide state and also caches transform nodes)
-- pass 1: for each LayerBuilder, transitively build and cache a transform chain
of a type (2d/3d) determined by the leaf (entry point) layer
-- pass 2: for each LayerBuilder, build the actual layer content render tree
and instantiate the layer controller objects

Rewrite program instructions so that each value becomes available as
late as possible, just before it's used by another instruction. This
reorders blocks of instructions to reduce them number of temporary
registers in flight.
Take this example of the sort of program that we naturally write,
noting the registers needed as we progress down the right:
src = load32 ... (1)
sr = extract src ... (2)
sg = extract src ... (3)
sb = extract src ... (4)
sa = extract src ... (4, src dies)
dst = load32 ... (5)
dr = extract dst ... (6)
dg = extract dst ... (7)
db = extract dst ... (8)
da = extract dst ... (8, dst dies)
r = add sr dr (7, sr and dr die)
g = add sg dg (6, sg and dg die)
b = add sb db (5, sb and db die)
a = add sa da (4, sa and da die)
rg = pack r g ... (3, r and g die)
ba = pack b a ... (2, b and a die)
rgba = pack rg ba ... (1, rg and ba die)
store32 rgba ... (0, rgba dies)
That original ordering of the code needs 8 registers (perhaps with a
temporary 9th, but we'll ignore that here). This CL will rewrite the
program to something more like this by recursively issuing inputs only
once needed:
src = load32 ... (1)
sr = extract src ... (2)
dst = load32 ... (3)
dr = extract dst ... (4)
r = add sr dr (3, sr and dr die)
sg = extract src ... (4)
dg = extract dst ... (5)
g = add sg dg (4, sg and dg die)
rg = pack r g (3, r and g die)
sb = extract src ... (4)
db = extract dst ... (5)
b = add sb db (4, sb and db die)
sa = extract src ... (4, src dies)
da = extract dst ... (4, dst dies)
a = add sa da (3, sa and da die)
ba = pack b a (2, b and a die)
rgba = pack rg ba ... (1, rg and ba die)
store32 rgba ... (0)
That trims 3 registers off the example, just by reordering!
I've added the real version of this example to SkVMTest.cpp.
(Its 6th register comes from holding the 0xff byte mask used
by extract, in case you're curious).
I'll admit it's not exactly easy to work out how this reordering works
without a pen and paper or trial and error. I've tried to make the
implementation preserve the original program's order as much as makes
sense (i.e. when order is an otherwise arbitrary choice) to keep it
somewhat sane to follow.
This reordering naturally skips dead code, so pour one out for ☠️ .
We lose our cute dead code emoji marker, but on the other hand all code
downstream of Builder::done() can assume every instruction is live.

Most hoisted values are used in the loop body (and that's really the
whole point of hoisting) but some are just temporaries to help produce
other hoisted values. This used_in_loop bit helps us distinguish the
two, and lets us recycle registers holding temporary hoisted values not
used in the loop.
The can-we-recycle logic now becomes:
- is this a real value?
- is it time for it to die?
- is it either not hoisted or a hoisted temporary?
The set-death-to-infinity approach for hoisted values is now gone. That
worked great for hoisted values used inside the loop, but was too
conservative for hoisted temporaries. This lifetime extension was
preventing us from recycling those registers, pinning enough registers
that we run out and fail to JIT.
Small amounts of refactoring to make this clearer:
- move the Instruction hash function definition near its operator==
- rename the two "hoist" variables to "can_hoist" for Instructions
and "try_hoisting" for the JIT approach
- add ↟ to mark hoisted temporaries, _really_ hoisted values.
There's some redundancy here between tracking the can_hoist bit, the
used_in_loop bit, and lifetime tracking. I think it should be true, for
instance, that !can_hoist && !used_in_loop implies an instruction is
dead code. I plan to continue refactoring lifetime analysis (in
particular reordering instructions to decrease register pressure) so
hopefully by the time I'm done that metadata will shake out a little
crisper.

This change adds another layer of complexity and control to
the particle system. There are now two code chunks: the old
code that's run per-particle, and new code that's run for
the effect itself. This allows for effect lifetime to be set
by the script (eg, randomly), as well as the emission rate.
Rate can vary over time (see pulse.json), and particles can
be emitted in bursts by setting the effect's burst field
(see fireworks.json).
Additionally, the effect has its own frame of reference and
color, which becomes the default state for newly emitted
particles. This allows synchronizing state across particles
in various interesting ways (see color in fireworks.json).

We're currently letting render context overrides (opacity, color
filters, blend mode, etc) spill down the descendent/mask content
tree.
This is not ideal, as mask content isolation breaks atomicity
assumptions for deferred overrides. Case in point: motion blur uses
SkBlendMode::kPlus to accumulate content "layers" - but since mask
content gets rendered into a separate layer, it fails to produce the
expected result.
The fix is to realize all context overrides on the top-level mask layer
(we already allocate this layer, so there's no reason to defer
downstream anyway).

This makes the register recycling checks a bit more
precise. At head we never recycle a register that's
holding a hoisted value, which is overly conservative.
We really should never recycle a register that's still
needed. By extending the lifetime of any hoisted value
that's used in the loop, we prevent that, while still
allowing hoisted values that are only used in hoisted
computation to be reused.
This takes just a small tweak in the JIT code (removing
the !hoisted({x,y,z}) checks), and a somewhat larger
refactoring in the interpreter, making both hoisted and
non-hoisted code go through the same recycling register
assignment flow.
There's one diff in the existing cases where we now
reuse a hoisted register, and I've added a second test
just to make sure it's covered explicitly.

Due to limitations in BodyMovin/AE JSX, full effect data is not
available (specifically the "channel range" property).
We only support static master hue, static master saturation and
static master lightness at this point.
This CL also introduces a new animation builder pattern:
DiscardableAdapterBase and attachDiscardableAdapter().
The former is a base class for adapters with full animator ownership.
This enables a) capturing raw adapter pointers in animator lambdas and
b) syncing to SG only once, after all local animators are updated).
The latter is a helper for managing adapter creation and optional
destruction (when all adapter properties are static we can discard it).

Add missing comparison and selection ops, bit casts, 16-bit memory
operations, gathers, uniform loads, and fill in math holes where
reasonable. Update some names to be a bit more regular.
I think all instructions are implemented in the interpreter,
and many tested. More testing and JITs to follow.

This removes all of the fixed-function particle affector classes.
Instead, each particle effect just has two SkSL snippets, one for
spawn logic, and one for update logic. Each one gets an inout copy
of the particle struct. Ultimately, this makes the effects much
simpler and smaller, while also being far more flexible (you can
do whatever you want with any values you want). Finally, because
the interpreter is vectorized and a particular effect's scripts
are usually tuned to the specific behaviors desired, it's faster
on basically every effect I compared.
I re-created all of the old effects in the new system. Many just
use pure SkSL (no curves or anything). Some of the old curve and
path/text stuff was very handy, though - so those are now exposed
as external values in the interpreter. Basically, an effect can
have any number of named "bindings" that are a callable thing.
This can be a path, text (shortcut for making fancy paths), curve,
or color curve. The path ones return a float4 with position and
normal, the curves return one or four floats.
... and this transposes all of the particle data storage into
SoA form, so that it can use the much faster interpreter entry
point.

Even if a JIT ultimately doesn't end up hoisting any values, it's going
to want this information while it decides. Writing it in one place also
ensures we only get it wrong in one place...
I'm no_ extending the lifetime of hoisted instructions here in Builder.
That's something to leave to the backend so they have the flexibility of
which of these values to hoist, if any. If they don't hoist, they'll
need to know when the value dies.
Moving this information back here lets the test expectation goldens
reflect the hoist bit again too. Kind of nice.

I'm slowly refactoring my way to where hoisting and register assignment
are done in backend-specific ways, but this liveness analysis is always
going to be useful for each backend.
