The ES3 spec doesn't mandate that `isnan` actually has to do anything,
so the Isnan test is not enabled. (It doesn't work on my personal
machine unless I make the NaN detectable at compile-time.)
We do not support these functions in constant-expressions, as we
currently avoid optimizing anything into a non-finite value; we leave
expressions alone if we calculate a NaN/inf result for their value.

Improved tests caught a longstanding bug in the compile-time
optimization logic for round/roundEven. These would *always* round to an
even number even when it didn't make sense to do so. (e.g. 3.1 would
round to 4.)
RoundEven isn't available in lower shader models of Direct3D;
SPIRV-Cross throws if it's unavailable. We may need a caps bit for this.

When compiling test shaders, we were setting SK_FRAGCOORD_BUILTIN on the
`coords` parameter to main() instead of SK_MAIN_COORDS_BUILTIN. These
two built-ins don't have the same type (float2 vs. float4) and don't
mean quite the same thing.
The SPIR-V code generator saw a variable with the SK_FRAGCOORD_BUILTIN
builtin value and assumed the presence of a global variable named
`sk_FragCoord`, which didn't exist (because it was never referenced in
the code, so it was never cloned in from the sksl_frag module).
This is only a concern when compiling test shaders with skslc; real
shaders don't hit these code paths. The generated code here is still
imperfect; if you look closely, you'll see the GLSL and Metal code is
referencing the `coords` variable but it's never declared anywhere.

The bottom half--`x, y, $genBType`--required adding basic support into
`evaluate_n_way_intrinsic_of_type` for mixed argument types, since `x`
and `y` could be of any numeric type, but `a` is always boolean.

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.
