As DSLWriter evolved, it ended up performing two unrelated duties:
1. Holding per-thread state which is referenced throughout SkSL
(including non-DSL code)
2. DSL-specific utility functions
There's no reason for those to be contained in the same class, and
there's also no reason the per-thread state should be held in a
DSL-specific class. This breaks out an SkSL::ThreadContext class to hold
the state info, leaving the DSL utility functions behind in DSLWriter
(which should perhaps be renamed, but that's a job for a future CL).

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.

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"

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);
}

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.

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.
