When coercing a type, we would previously call checkValid() so we could
detect function-references and type-references, so we could get a nicer
error message.
It turns out that we can just do the "is this a type-reference/
function-reference?" check directly inside coerce() and get the same
improved error messages. Since we should be coercing all our values to
the right type, and type/function-references aren't coercible to
anything, this should catch them all. I don't expect any of these
to survive all the way to the end of IR generation.
(In case one of these types does slip through, I've left the error case
in checkValid, but I've also put in an assertion. If the fuzzer can
make that assertion fire, we are probably missing a call to coerce()
somewhere.)
This cleanup is meant to help migrate coerce() out of IRGenerator.

When SPIR-V generates function calls to an intrinsic, it assumes that
it can get a pointer to out-parameters referenced by the intrinsic.
This does not account for swizzled out-parameters; these are valid
lvalues, but do not work with getPointer().
The two intrinsics supported by SkSL which have an out-parameter are
frexp and modf, so these tests were fleshed out to trigger the error.
Neither of these are supported in ES2, though, so we cannot test them
via Runtime Effects.

The out-param helpers emitted by the Metal code gen (intended to provide
GLSL out-parameter semantics in Metal) emitted bad code if passed the
same variable for two separate out parameters. It would previously
create two parameters in the helper with the same name. The helper
function now omits the name of the second variable in the parameter list
if it is redundant; we already know the caller is passing the same

GLSL ES2 documentation on out parameters: "Evaluation of an out
parameter results in an l-value that is used to copy out a value when
the function returns."
The inliner does not do any alias checking when inlining an `out` param.
That is, passing the same variable to two separate `out` parameters
would not generate two distinct lvalues in the inlined code; it reuses
the same variable for each out-params in the inlined code.
(Amusingly, our CFG can fully optimize away this test code so it just
returns "red".)

Multi-dimensional arrays aren't legal in GLSL/SkSL, so this should be
caught and flagged as an error. The parser now verifies that a
variable's type isn't an array-type before accepting a `[` token to
open an array on the variable name.
This CL also refactors the IR generator's `convertArraySize` method to
make sure that various checks are made for all callers. Originally this
restructuring was used to verify array multi-dimensionality, but that
didn't detect errors inside struct declarations (which get no error
checking inside the IR generator) so the IR generator updates no longer
need to check the array dimensions.

The CL at http://review.skia.org/366399 introduced a bug with
LValue::getPointer. Specifically, getPointer used to return zero when
no pointer is available. (This happens when the LValue is a swizzle.)
That CL changed the error code to -1. However, it did not fix up all
the call sites that checked the return value of getPointer().
This CL fixes up those call sites to use -1 consistently, and adds
TODOs in spots which do not check the result from getPointer() at all
(instead assuming it cannot fail). This will allow swizzled out-
parameters to work in SPIR-V as they did before. (Except in intrinsics,
where they seem to have been broken all along, but those are now marked
with a TODO at least.)
Note that we still do not fully emulate GLSL semantics for out
parameters, as out-parameters should only be copied back to the original
variable at the end of the function call to be fully GLSL compliant.
(This CL also replaces a tuple with a named struct for readability.)

This uncovered a bug in Metal code generation of `matX *= matY` which is
now fixed. (It was emitting the helper function more than once.)

Previously, our only test was invoking `sin(1)` which is a pretty
ineffective test. Now, we test args and return types for all the basic
scalars/vectors/matrices.

These are basic vector types, required by GLSL ES2, but we could not
create helper functions using them because they were missing from our
GrSLType enum. (This also prevented Runtime Effects from using these
types in helper functions.)

These tests have updated to return green on success, or red on failure.
Some tests were modified slightly to conform to ES2 limitations, or
split into separate ES2 and ES3 parts.

We already had this trick for scalar integers, this extends it to
integer vectors. As with prior work in this area, it would be better to
detect this case and produce an error, but now we at least produce
consistent and well-defined results (rather than undefined signed
integer overflow).

The test has been split into an ES2 version and ES3 version; the ES2
side omits unsupported integer ops like << >> & | ^ %.
