eb68973c2f Disallow matrix ctors which overflow a column.
The GLSL spec allows matrix constructors containing vectors that would
split between multiple columns of the matrix. However, in practice, this
does not actually work well on a lot of GPUs!

- "cast not allowed", "internal error":
	Tegra 3
	Quadro P400
	GTX 660
	GTX 960
- Compiles, but generates wrong result:
	RadeonR9M470X
	RadeonHD7770

Since this isn't a pattern we expect to see in user code, we now report
it as an error at compile time. mat2(vec4) is treated as an exceptional
case and still allowed.

Previously the magic surrounding sk_RTAdjust was inaccessible to the
DSL, meaning that the DSLParser would not work properly when the
sk_RTAdjust field was present in an interface block. This refactoring
means all interface blocks are processed via the same path.

f8a550491e SkSL: Use type-specific sampling intrinsics, rather than fn-call syntax
After further discussion, using intrinsics with signatures similar to
sample keeps us looking like GLSL. However, using "sample" is still
misleading, so this adds explicit "shade", "filter", and "blend"
intrinsics. After migrating clients, the "sample" versions will be
removed.

eb0f29dba2 SkSL: Allow invoking children (shaders, etc) like functions
Previously, you would declare child objects (shaders, colorFilters, etc.)
and "sample" them like this:

    uniform shader input;
    uniform colorFilter filter;
    half4 main(float2 coord) {
        half4 inColor = sample(input, coord);
        return sample(filter, inColor);
    }

With the new syntax, those child objects become directly callable,
reflecting the way that Skia assembles all parts of the paint (as functions)
in the overall fragment shader:

    uniform shader input;
    uniform colorFilter filter;
    half4 main(float2 coord) {
        half4 inColor = input(coord);
        return filter(inColor);
    }

4a5e22a8c8 Further unified error handling between SkSL and DSL
This eliminates the SkSL ErrorReporter class and funnels everything
through the DSL ErrorHandler. Since the DSL error handler can be
changed, this required a number of updates to ensure that things work
properly in the face of custom error handlers. There is probably more
work to be done in that area, but this at least passes all existing
tests.

a40ddcd63d Pass dsl::PositionInfo by value
We were previously using a mix of pass-by-value and pass-by-pointer (to
allow for explicitly null PositionInfo). Being able to pass a null
PositionInfo didn't really add much, since we can just use a nullary-
constructor PositionInfo instead, so these have all been migrated to
by-value.

a2d22b2e08 Broke DSLVar into separate subclasses
Previously, DSLVar represented local, global, and parameter variables.
This splits it into three separate subclasses.

In addition to just being a cleaner API in general, this also addresses
an issue we ran into with the upcoming DSLParser: previously, a global
DSLVar's storage was not set correctly until DeclareGlobal was called,
so an AddToSymbolTable call prior to DeclareGlobal would create the
SkSL variable with the wrong storage, causing spurious errors on
global-only modifiers. But holding off on the AddToSymbolTable tends to
break constructs like "int x = 0, y = x", so improving the API seemed
like the best way to address it.

Now that we have greater type safety around variables, we can
potentially avoid having to call AddToSymbolTable for DSLVar and
DSLGlobalVar altogether, since we know they are both supposed to end up
in the symbol table, but that isn't something I want to change in this
CL.

55a63afc5f Make it possible to use the DSL from within the compiler itself
The DSL would not previously function within the compiler, because it
expected to be in charge of everything itself. The compiler and DSL also
disagreed about how to handle some things, such as the DSL not
respecting the compiler's override flags.

This CL moves responsibility for much of the setup process into
DSL::Start(), which the compiler now invokes. DSL::Start() now also
takes a ProgramSettings instead of DSL-specific flags, and the
externalFunctions vector has been moved into ProgramSettings.

This adds some basic flags to the DSL initialization which allows us to
toggle things like optimization and validation.

This includes several new array variants of existing APIs, DSLBlock now
supporting SymbolTables, and a couple of other minor changes needed by
the upcoming DSLParser.

c9125aa8f3 Reland "Better first-class shader & color filter support in runtime effects"
This is a reland of adadb95a9f
... adds a temporary workaround for some Android framework code.

Original change's description:
> Better first-class shader & color filter support in runtime effects
>
> This does a few things, because they're all intertwined:
>
> 1) SkRuntimeEffect's API now includes details about children (which Skia
>    stage was declared, not just the name). The factories verify that the
>    declared types in the SkSL match up with the C++ types being passed.
>    Today, we still only support adding children of the same type, so the
>    checks are simple. Once we allow mixing types, we'll be testing the
>    declared type against the actual C++ type supplied for each slot.
> 2) Adds sample variants that supply the input color to the child. This
>    is now the only way to invoke a colorFilter child. Internally, we
>    support passing a color when invoking a child shader, but I'm not
>    exposing that. It's not clearly part of the semantics of the Skia
>    pipeline, and is almost never useful. It also exposes users to
>    several inconsistencies (skbug.com/11942).
> 3) Because of #2, it's possible that we can't compute a reusable program
>    to filter individual colors. In that case, we don't set the constant
>    output for constant input optimization, and filterColor4f falls back
>    to the slower base-class implementation.

371f6e18e5 Refactored SkSL function creation and error handling
This breaks up the giant IRGenerator::convertFunction method into more-
manageable chunks, moves the functionality into FunctionDeclaration,
and funnels the DSL through it so it receives the same error checking.
