2e25ff436a Directly compute call counts, rather than mutating state
This causes a ~4% regression on sksl_large, but some of that
can be bought back in two ways:

1) Removing (now unnecessary) cloning of program elements
2) Hoisting the new analysis passes, with (nontrivial)
   logic to update/maintain the call counts as we edit IR.

Also, this fixes bugs where we were emitting functions that
had "calls" from no-longer called functions.

0f37907ac7 Undo call-count fix for intrinsic functions.
This CL is conceptually a revert of http://review.skia.org/320258,
although the code has changed shape a bit since that CL was landed.

This fix was too aggressive, and can lead to functions being dead-
stripped while they still have an active reference.

371fde549e Rename 'DefaultSettings' golden outputs to 'StandaloneSettings'.
I realized that "DefaultSettings" as a name suffix was unclear, because
"Default" is a different settings mode from skslc running with
--nosettings.
In --nosettings mode, skslc uses "standalone" settings.

0ed9f31f6a Migrate several GLSL workaround unit tests to golden files.
We now support building an SkSL golden output twice, once honoring the
custom #pragma settings, and once more ignoring the settings. This
allows us to see the output of the workaround technique, alongside the
"default-settings" output which should not contain a workaround.

To implement this, skslc now supports a flag: --[no]settings.
When it's set, /*#pragma settings*/ comments are honored. When it's not
set, skslc ignores the comments. compile_sksl_tests.py passes this flag
along to skslc.

This approach is not strictly limited to workarounds; the
"TypePrecision" GLSL test was also updated to use this technique.
