cf3059e719 Convert IRGenerator::convertIf to IfStatement::Make.
This lets the Rehydrator and Inliner benefit from static optimization
opportunities, like converting `if (false) {...}` to a Nop.

e1d1b08203 Migrate convertSwitch to SwitchStatement::Make.
This splits switch() construction into two stages.

- One version of Make takes an array of case-values and case-statement
lists, and is responsible for reporting errors if the case-values are
not unique or are improperly typed. This is what the IR generator or DSL
will start with on its first encounter with the switch statement.

- The other version of Make takes an array of already-processed
SwitchCases and can assume the invariant that they're all correctly-
typed with unique values. This is what we will have when a statement
is inlined or otherwise cloned. (We still assert this invariant, for
correctness' sake, but in release mode we assume it.)

This CL doesn't perform any optimizations at Make time yet; it does work
equivalent to how `switch` works in the IR generator today. It does
improve duplicate case-label checking slightly; duplicate case labels
are now reported, and duplicate `default:` labels are detected.
(Multiple `default` labels won't pass the parser, but they can be
constructed in DSL.)

6e88e041d9 Migrate convertSwizzle to Swizzle::Make.
There are two forms. Swizzle::Make supports components XYZW only;
Swizzle::MakeWith01 also supports the 01 components, and restructures
the zeros and ones into a constructor (as IRGenerator::convertSwizzle
has historically done). This means that once we are past the initial
IR generation stage, and we know that the 01 components have been
eliminated, we can avoid the extra 01-handling logic and just call
Swizzle::Make directly. This isn't a huge deal but it means that call
sites like the inliner can avoid some extra work that will never happen.

e8a2492b68 Migrate DefinitionMap logic to its own class.
This doesn't change any functionality. It just compartmentalizes a large
chunk of logic that was previously intertwined in the Compiler class.
This logic stands alone and doesn't need anything from the Compiler at
all except the generic "Defined" expression from the Context.

In followup CLs I intend to experiment with changes to the API and
logic, but factoring the code out seemed like a big enough change that
it deserved its own CL.

remove them from the context entirely, but it gives them a dedicated

be0b3b7363 Strip down SkSL::ExternalValues, limit them to functions
Previously ExternalValues were flexible, and could be used as raw values
(with the ability to chain access via dot notation), or they could be
callable. The only non-test use-case has been for functions (in
particles) for a long time. With the push towards SkVM, limiting
ourselves to this interface simplifies things: external functions are
basically custom intrinsics (and with the SkVM backend, they'll just get
access to the builder, and be able to do any math, as well as
loads/stores, etc).

By narrowing the feature set, we can rename everything to reflect that,
and it's overall clearer (the SkSL types now mirror FunctionReference
and FunctionCall directly, particularly in how they're handled by the
CFG and inliner).

0a442b71b0 New SkSL code generator that emits directly to skvm
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.

dc75a97b80 Add global struct definitions to SkSL.
Previously, GLSL and Metal code generators would emit a struct wherever
the type was first used in the code, regardless of where it was
originally defined or what scope the type needs to live in. This CL adds
a ProgramElement for struct definitions, so that structs will now appear
at the top-level as they were originally defined. In the case of Metal,
some special handling is also needed to handle the Globals struct
properly.

Not yet fully supported:
- No special handling for structs declared inside functions yet
- No support for structs in separate scopes with overlapping names
The severity of the remaining issues depends mostly on whether we want
to support structs inside functions in Runtime Effects.

71624de2c5 Allow constant propagation for negated constant-vectors and ints.
This CL improves on the previous fix for oss-fuzz:26789 by actually
propagating the negation from the PrefixExpression inside the
constructor, which unblocks further optimizations.

Interestingly, this fix also exposes a further missing optimization--we
optimize away comparisons of constant-vectors for floats, but fail to
do the same for ints.

569249be6c Improve support for function prototypes in SkSL.
Previously, when a prototype was parsed, this added a function
declaration to the symbol table, but the prototype itself was not
re-emitted during code generation. This meant that the final code might
not be valid, since the absence of prototypes meant that the code might
attempt to invoke a function before its declaration. Now, prototypes are
stored in the ProgramElement list and re-emitted during code generation
for GLSL/Metal/CPP. (SPIR-V doesn't name its functions at all.)
