This analysis pass assumes we have a program with a valid structure--all
loops must be ES2-compliant, and all function-calls must reference real
functions that exist. If we detected an error during compilation, our
program might not meet these criteria.

Calling `visitProgramElement` on a FunctionDefinition should always set
fFunctionSize on any path through the code. However, this is difficult
to confirm by inspection, since there are several exit conditions. It's
safest to initialize the variables at construction time, just in case.

This moves the swizzle domain test into the path used by the DSL so that
the error check benefits both sides. To make this possible we need to
be able to distinguish between equivalent swizzle components like x and
r, so they aren't collapsed down to the same component until the very
end.

Previously, deeply-nested loops could lead to stack overflow during SkVM
dead-code elimination. The DCE algorithm in SkVM now stores its worklist
on the heap and does not rely on recursion. Since we now enforce an
upper bound on maximum program size within SkSL, this worklist's size
should always be reasonable and bounded.

Our program-size analysis pass needs to recurse into called functions;
depending on the exact order of functions in the program, this recursion
can hypothetically be as deep as the deepest function-call chain. Set an
upper bound on recursion here, so we don't overflow the stack while
trying to check the program size. In practice, 50 frames is far deeper
than a regular shader should ever go.

The previous version of the code would actually end up skipping over
recursive code silently. (In fact, CheckProgramUnrolledSize is always
called immediately after Analysis::DetectStaticRecursion regardless of
whether or not any cycles were found, and the "cycle detected" assert
was not firing.) The code now actually detects cycles correctly; this
can be verified by uncommenting the call to error().
In a followup CL, I will improve the error reporting so that the cycle
is tracked and can be reported. Right now, we can detect a cycle but
don't keep a copy of the stack.

The fuzzer is currently learning to make unboundedly-large programs by
nesting medium-size loops repeatedly. SkVM doesn't have a mechanism to
limit the ensuing explosion of code and ends up making unreasonably deep
stacks and/or unreasonably large programs.
SkSL now enforces an upper bound of approximately 100,000 IR nodes on a
fully-flattened, fully-inlined strict-ES2 program. The limit is picked
out of thin air, but this should be enough to prevent SkVM from going
haywire while still being large enough to handle any reasonable program.
We can definitely tune this value if we find that it is too large
(admitting dangerous code) or too small (rejecting good code).

Most of the logic in IRGenerator::finish has moved to
Compiler::finalize. The @if/@switch pass has been combined with the pass
that verifies no dangling FunctionReference/TypeReference expressions,
saving one walk through the IR tree. Most program-finalization logic now
exists in Compiler and Analysis.
This change reorders our error generation logic slightly, and manages to
squeeze a few extra (valid) errors out of one of our fuzzer-generated
tests, but is not really intended to affect results in any significant
way.
