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).

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.

That's something to leave to the backend so they have the flexibility of

Moving this information back here lets the test expectation goldens

2) Introduce MotionBlurController to swap for a regular LayerController

Instruction is the fundamental data, and Analysis derived from it.
The fields in Analysis are only* needed in Builder::done(), and this

No speed change as far as I can tell.
* As you may notice looking at the test expectations, making analysis
ephemeral means that dump() can no longer print the skull for dead code
or the arrow for hoisted. The register program that's also in the
expectation file still reflects both of these optimizations, so we're
not really losing any information. Just maybe less demo-friendly.

- feather -> draw the content into a separate layer, then blend (dstOut) the composed

Kind of the flip side of pack.
Made slightly awkward by instructions having only one immediate...
calling _BitScanForward / __builtin_ctz() at runtime seems to work
fine, but it really could have been done at compile time.

This instruction can lower to some useful SSE/NEON
instructions, and even if not, is a handy way to
express the frequent paring of << and |.
I32_SWAR: 2.3 -> 1.9
I32: 2.6 -> 2.4
F32: 5.1 -> 4.7

Another way for an interpreter to go faster
is to provide better instructions.
mul_unorm8 is one we use all the time.
Drops _I32 bench from ~3.6ns/px to ~2.6ns/px.

Eliminate the duplicate functionality,
and better testing for the bench builders.

This is mostly to test how easy rebaselining SkVMTest is.

The interesting bit here is a change in glyph positioning:
AE text animator transforms are to be applied relative to the glyph position.
To support this behavior, update Shaper to externalize glyph positioning
when in fragmented mode. I.e. instead of baking glyph positions in blobs,
apply them at the scene graph transform level (such that they compose with
animated transforms correctly).

Limitations:
- no range selectors (applies to the whole text)
- only position, fill color and stroke color for now
