Add support for #pragma settings comments in SkSL. This will allow us to write skslc-based golden tests that deviate from the standalone skslc settings. This CL provides six options; more will be added as necessary. - Default (caps) - UsesPrecisionModifiers (caps) - Version110 (caps) - Version450Core (caps) - ForceHighPrecision (settings flag bit) - Sharpen (settings flag bit) Change-Id: I9b779e039b2f0c0ccf43dca226fb4844aff3526b Reviewed-on: https://skia-review.googlesource.com/c/skia/+/317237 Commit-Queue: John Stiles <johnstiles@google.com> Auto-Submit: John Stiles <johnstiles@google.com> Reviewed-by: Brian Osman <brianosman@google.com> 2020-09-16 21:43:11 +00:00			`#version 400`

Remove usage of sqrt() as an optimization barrier in tests. In the majority of cases, a uniform is an equally good substitute, and replacing `sqrt(N)` with `unknownInput` actually makes the test clearer.
