This node was only used to detect recursion while inlining. We no longer
need to do this, because we disallow recursion in all programs.
The removal of one IRNode per inlined function actually allows for
slightly more aggressive inlining, since we restrict inlining based on
IRNode consumption. This allows the "ExponentialGrowth" tests to inline
a bit more deeply than before.

SkSL::Operator was previously just a thin wrapper around Token::Kind and
everything was therefore written in terms of Token. Since Token is not
accessible from include/ (and we don't want it to be), this creates an
actual Operator enum and eliminates the dependence on Token. This will
enable followup changes to reference Operator from within the DSL
include files.

Trying to land on more consistent terminology:
- builtin: Any symbol or program element that's declared in the one of
the modules/pre-includes.
- intrinsic: The specific functions that are declared, but not defined
in the modules. These are implemented by the generators.
- builtin functions: Use this to refer to functions that are both
declared and defined in the modules. (eg unpremul)
Note that Module is still a term, and that may go away as well. This was
focused on reducing overloaded terminology around the elements
themselves (and not referring to things like "unpremul" as an intrinsic,
in the case of "referencedIntrinsics").

SkRuntimeEffect needs an API for generating debug traces. This means
that we will need references to debug traces inside a public header.
Rather than reference SkVMDebugInfo directly, we now have a simpler
base class for debug traces. This is better suited to landing in
include/.
I've also renamed SkVMDebugInfo to SkVMDebugTrace for consistency, since
it now contains all the trace data. (When it was first added, it only
had the slot info.)

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 fuzzer found that we constructed TypeReferences without first
checking for disallowed tyoes. (In fact, TypeReference creation had no
error checking at all; it didn't even have Convert/Make functions.)
Added proper Convert/Make to TypeReference, and used those calls to
report errors or cause assertions if trying to make a TypeReference to a
type that the program did not support.
(While tracking down this bug, I added strict-ES2 type assertions to our
constructor IR nodes as well. This helped pinpoint the error and seem
reasonable to leave in, just in case.)

No functional changes, just continuing the process of moving code out
of IRGenerator in hopes of its eventual disappearance.

Now that DSLParser is used for everything we can get rid of this
unused code.

Throughout SkSL we've begun using doubles as a convenient way to store
any SkSL value (int, float, bool) in a single type. This idea has now
been extended to literals. Rather than having three expression kinds for
integers, floats and boolean literals, we can have just one. These can
be accessed in a type-specific way (`floatValue`, `intValue`, and
`boolValue` return the expected type, or assert if it's not the
matching type), or in a type-agnostic way (`value` will return a double
and works on any type of Literal).
This allows us to remove a complex template trick (Literal<T> is gone),
removes two redundant Expression types, and and lets us reduce our code
size in ConstantFolder, FunctionCall, etc.
Most of the conversion process was pretty straightforward:
* `IntLiteral::Make` becomes `Literal::MakeInt`
* `x.is<IntLiteral>()` becomes `x.isIntLiteral()`
* `x.as<IntLiteral>.value()` becomes `x.as<Literal>.intValue()`

This is a first step towards replacing `finalizeFunction` with a
`FunctionDefinition::Convert` method living outside of the IRGenerator.
Previously this code would assert that we had no early returns from a
vertex-program main() method; this has been turned into an error.
(The original assertion was also tied to fRTFlip, because the *problem*
with early-returns in main is tied to the lack of RTFlip fixups, but
we fundamentally don't allow early returns, so it makes more sense to
just universally disallow it.)

The entire ASTNode is probably going away soon, but this is a decent
place to start. Checking the fuzzer logs, we had 0% coverage in here,
which makes sense because it's unreachable by any normal means.
