(This CL also adds modulo to the IntFolding shared test, since this was
absent from the test. It's implemented and working properly already.)

There's no functional change here; it's just using a slightly higher-
level abstraction to pass the same payload.

GLSL requires that functions are declared before first use. In most
cases, we avoid the requirement for explicit prototypes by this by
strategically ordering our functions within the emitted code, but an FP
file might reference its helper functions in any order or have helper
functions that cross-invoke each other, so prototypes should be emitted.

This is necessary to support function calls in FP files properly; in
some cases, functions can be referenced before they have been emitted,
and we need to be able to name them.
This CL resolves the remaining errors in GrRecursion.cpp. There are
still additional errors in GrNestedCall.cpp that will be fixed in
followup CLs.

Previously, we'd just emit functions with `%s` in their function bodies.
Also, the fFormatArgs wouldn't get cleaned up, so subsequent code would
fill in the wrong format arguments in each place.
There are still problems with function calls (`sample` is broken;
function names are accessed before they've been declared or initialized)
but this is a step in the right direction.

`func1` and `func2` emit bad code, `return %s()`, and because they don't
consume their `%s` format argument. This leaves the format argument list
unbalanced and all future args are wrong.
Another serious problem is that we don't actually know the names of the
functions that they need to call, because we haven't emitted them yet.
`func3` is not emitted at all. Sampling from a fragment processor
apparently fails in this context.
This is a more general case repro for skia:10684--it turns out that
recursion in particular wasn't the issue, but nested function calls just
don't work properly at all in FP files. This wasn't an issue in practice
because we don't have any existing FP files which nest function calls,
and the inliner also tends to aggressively flatten everything out if we
don't explicitly disable it.

This reverts commit 941fc7174f.
Reason for revert: performance now seems to be roughly equal or better
(~1%) over several trials.

Golden SkSL outputs are intended to eventually replace the majority of
our unit tests, since they can automatically update themselves when we
change implementation details of the compiler.
If you change the compiler output without updating the Golden files, the
CheckGeneratedFiles housekeeper will be triggered. Set
`skia_compile_processors` or `skia_compile_sksl_tests` to true in your
GN args to regenerate them.
Almost all of the tests from SkSLFPTests.cpp and SkSLGLSLTests.cpp can
be migrated into separate unit-test .fp/.sksl files in a followup CL.
hcm@ has signed off on removing the copyright boilerplate preamble from
our unit test files.
