We need to rescan after optimizing away expressions that might exist
in the CFG/definition map, since we are rebuilding them from scratch and
not just stripping off excess parts from them.

This maps to usage better, and makes some code simpler to understand.
Note that there is still a PipelineStage *back-end*, which is specific

generate a PipelineStage (for the GPU backend), or an skvm program (for

No known clients (CanvasKit, Android) want to ignore the exif
orientation in an animation.
A follow-on CL will deprecate SkAndroidCodec::ExifOrientation, leaving
it up to the client (e.g. SkAnimatedImage, hwui/ImageDecoder) to
handle the orientation. Add SkEncodedOriginSwapsWidthHeight to assist
clients to do so.
Update stoplight_animated_image GM. It previously showed using
SkAnimatedImage without respecting the orientation, which is no longer
supported. The new version replaces the left half of the image with the
right.
Remove assert that is no longer true. Originally, an SkAnimatedImage was
"simple" if it did not have a crop or postProcessor. This is no longer
true if has an exif orientation. Add a test that calls the simple
constructor and verifies it does not crash.

Ops should report HasAABloat::kYes if they use coverage AA approaches.
This was confusing the new GrClipStack into thinking a subpixel path
(that should have been coverage) was non-AA, and in certain transforms
this would then not touch pixel centers and the clip stack would reject
the draw early.

Rather than return a complex ternary expression, we now assign the
complex expression into a variable and then return that variable.
This works around a bug in the Adreno driver where it fails to parse
"(complex-expression).swizzle" and errors out with "Cannot offset into
the vector." Instead, we now store the complex expression into a
variable and return that variable. This changes the final assembled
code into a two-parter, "float2 v = (complex-expression);" followed by
"v.swizzle". This is easier for the Adreno driver to swallow and works
around the error seamlessly.

Because we use `continue` for flow control handling now, we can escape
from the middle of a switch statement. This wasn't possible when we used
`break`.
This unlocks some pretty stellar optimization opportunities if the
switch value can be determined at compile time; see BlendEnum for an
example.

When we determine that a function only contains a single return
statement and it is at the top level (i.e. not inside any scopes),
there is no need to create a temporary variable and store the
result expression into a variable. Instead, we can directly replace
the function-call expression with the return-statement's expression.
Unlike my previous solution, this does not require variable
declarations to be rewritten. The no-scopes limitation makes it
slightly less effective in theory, but in practice we still get
almost all of the benefit. The no-scope limitation bites us on
structures like
@if (true) {
return x;
} else {
return y;
}
Which will optimize away the if, but leave the scope:
{
return x;
}
However, this is not a big deal; the biggest wins are single-line
helper functions like `guarded_divide` and `unpremul` which retain
the full benefit.

Still TODO:
- Function calls. Can do these by inlining everything (recursively).
- Additional flow control: ES2 for loops can be supported (via
unrolling), and switch() can be implemented. (Was never done in
ByteCode).
- Uniforms and params have been set up to work very generically (caller
just supplies IDs, the generator collates everything into a master
working list). Builtins should work the same way (caller supplies a
map of builtin ID -> skvm::Val[]?), so that we don't need a special
case for device coord.
- Figure out integer type policy. Today, it's a mix of only supporting
signed integers, and just treating all integers as signed, even if
they're not.
- Now that defining intrinsics is *much* simpler, stop defining so many
of them in sksl_public.sksl, and just implement them here.

Fortunately, this had an existing opcode, so it was easy to add to our
intrinsics list, and the rest automatically worked.

We are still missing an implementation for Metal and SPIR-V, but at
least it's correct on GLSL now.

The shadowRec bounds code didn't handle directional lights, that's now
fixed. Also fixes normalization of the light direction -- it was only
using two components, it should use all three.

Implement per-character position attribute lookup based on [1]:
- convert "x" and "y" attributes to arrays
- introduce ScopedPosResolver to handle positioning attribute lookup
and fallback
- push a new resolver every time we enter a text positioning element
scope (<text>, <tspan>, etc).
- flush/reposition a new text chunk every time we encounter explicit
absolute positions
The position attribute fallback logic is complex enough to warrant a
unit test.
