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.

Performance experiment: disable control-flow analysis. This CL will be used to test for potential performance regressions (or improvements) that we might cause by disabling this optimization pass. It will be reverted in ~1 day.
