If we encounter code like `return 1; return 2;` we need to synthesize a

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.

- 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).

These enforce stricter rules about the signature of main, and each one
uses a separate pre-include module. That prevents color filters from
being able to reference sk_FragCoord (or coords passed to main) at all.
It also limits the versions of sample() that are exposed.
In the new world, an effect created for a specific stage of the Skia
pipeline can only be used to create instances of that stage (SkShader or
SkColorFilter). For now, SkRuntimeEffect::Make uses kRuntimeEffect,
which continues to be more lenient and allow creation of either shaders
or color filters from a single effect. After we migrate all clients, we
can deprecate and then delete that mode.

The long term goal is for the DSLCPPCodeGenerator to replace the
CPPCodeGenerator entirely, but we will need both to coexist while DSL is
still under development.
Currently, the DSLCPPCodeGenerator is cloned from CPPCodeGenerator and
emits almost exactly the same code (it adds a comment at the top to
distinguish its output). Its output will change in followup CLs.
This CL also allows skslc to recognize the `_dsl.cpp` output suffix and
generate code using DSLCPPCodeGenerator instead of CPPCodeGenerator.
This allows test DSL FPs to be created for inspection.

ConstructorComposite is a slight rework of ConstructorVector;
mechanically, both vector and matrix composition behave the same and
can share the same logic.
The generated code in SPIR-V and Metal still has some tweaks due to
different handling for matrices in these languages, but the SkSL
internal model mimics GLSL's view that vectors and matrices can be
created by lumping together any mix of scalars and vectors.
The backends will continue to adapt this model to their reality.

This shook out a long-standing bug; constant folding would treat a
matrix resize as if the cells not covered by the original matrix were
all zero. This is wrong; GLSL populates the unknown cells with an
identity matrix. We actually tested for the wrong behavior, so the tests
were updated to match the correct behavior, and an equivalent test was
added that does not constant-fold (to verify that our constant folder
matches reality).

Making a VectorCast from a compile-time constant will perform the cast
at compile-time instead; previously, we did not apply this optimization.
This simplified a few test outputs in subtle ways. (In particular, the
SPIR-V codegen used to occasionally decorate OpConstantComposite of
constant numbers with RelaxedPrecision, and no longer appears to do
this. This should have no effect on results either way AFAICS.)
Because we don't return VectorCast constructors containing compile-time
constant values, we do not need to implement compareConstant for this
constructor; they only wrap non-compile-time-constant expressions.

We don't directly support this today at all. In practice, though, simple
constant arrays are detected as equal in the constant-folding pass
because they hit the `x == x` self-equality check (using
`IsSameExpressionTree`).
This does not work for our inequality tests, though, so those do not
fold.

This allows me to separate the wrapper around the ID3D12PipelineState
from the other data we track with GrD3DPipelineState. In this way I can
create a GrD3DPipeline directly for compute experiments without worrying
about managing graphics-specific objects. In the long run, we'll
probably need GrD3DGraphicsPipelineState and GrD3DComputePipelineState.

As soon as a single VarDeclaration is successfully created, its Variable
is added to the current symbol table. However, if a variable-declaration
line declared several variables in a row, we would stop if ANY of the
declarations contained an error and discard the entire statement, but
would continue processing the rest of the program. This left us in a
position where some Variables existed in the SymbolTable with valid,
reachable names, but their corresponding VarDeclaration statement had
been thrown away as erroneous. Since Variables point back to
VarDeclarations for their initialValues, this gave us a stale pointer.
Any future reference to that variable name which could trigger an
access to its initialValue would read from this dead pointer.
This CL fixes the conversion of VarDeclarations so that we no longer
throw away any VarDeclarations associated with a successfully-parsed
Variable.

(compared to GLSL, where mediump matrices and floats do evaluate all
intermediate values at mediump).
This caps bit will be enabled on ARM GPUs and, in a followup CL, will
be used to toggle a workaround where `m*v` is rewritten as the sum of
(m[0]*v[0] + m[1]*v[1] + ... + m[N]*v[N]).

This allows us to remove 100 LOC from the inliner and is very unlikely
to affect any existing benchmark. We don't have any evidence to support
the idea that a one-iteration `for` loop with `continue`-based exits
will be any faster than a standard function call on any existing GPU.
Our fragment processors are generally written to avoid early returns,
in large part to avoid hitting this path.
This drastically impacts BlendEnum.sksl (which can no longer flatten out

Block::Make always makes a real Block object. This is important because
many callers rely on Blocks specifically; e.g. a function body must be a
scoped Block, nothing else will do.
However, unscoped Blocks are just a collection of Statements and usually
have more flexibility. So, Block::MakeUnscoped is a factory function
that will return the Statement as-is for a single-statement unscoped
Block. For an entirely empty Block, MakeUnscoped returns Nop.

This converts ccpr to just a poorly named atlas manager. The atlas
gets rendered by normal calls on its MSAA draw context:
for (;;) {
surfaceDrawContext->stencilPath(); // Stencil.
}
surfaceDrawContext->stencilRect(atlasBounds); // Cover.

This enables the ternary to be optimized away in code like:
const bool SHINY = true;
color = SHINY ? add_shine(x) : x; // to --> `color = add_shine(x);`
Without constant propagation.
Also, I added a unit test for ternary expression simplification; I
wasn't able to find an existing one.
When the optimization flag is disabled, this CL actually removes the
optimization of `true ? x : y` --> `x` entirely; previously, this
substitution would be made regardless of optimization settings.

Makes SkImage_Gpu backed by two proxies, an original and a copy. The
image uses the original until a new render task is bound to it at which
point further uses of the image will use the copy. If the image is ever
used off a GrDirectContext we fall over to the copy. If the copy is
never used and never can be used by the next flush then the render
task that populates it is marked "skipped" and we don't perform the
copy.

This check now runs at function finalization time, before constant
propagation has occurred; this affected the "DeadIfStatement" test.
Our detection isn't smart enough to realize that a loop will run zero
times, so it treats `for` and `while` loops as always running at least
once. This isn't strictly correct, but it actually mirrors how the CFG
implementation works anyway. The only downside is that we would not flag
code like `for (i=0; i<0; ++i) { return x; }` as an error.

GrThreadSafePipelineBuilder is the generic, base object the
GrContextThreadSafeProxy will hold. Each backend will create a
backend-specific version that is shared between the direct context
and the (possibly many) utility contexts.
Right now GrThreadSafePipelineBuilder just holds the pipeline
creation stats. Relatedly only GrGLGpu::ProgramCache and
GrVkResourceProvider::PipelineStateCache currently derive from
the new class (since they are the only backends that generate
pipeline stats).

In http://review.skia.org/375776, an optimization was added to the
Inliner, causing it to skip generation of unnecessary temporary
variables. The fuzzer immediately discovered a flaw in this logic: the
"unnecessary" variable was actually used in the rare case that a
function failed to actually return a value. The inliner didn't detect
this case. Of course, this isn't a valid program either, so now we
report the error and cleanly fail.
