Add helper uniforms to Runtime Effect tests. This lets us use descriptive names like `colorRed` and `colorGreen` instead of `half4(1,0,0,1)` and `half4(0,1,0,1)`. It also lets us use actual unknown values instead of synthesizing sorta-kinda-unknowns by calling sqrt.

Implement constant folding for (bool == bool) and (bool != bool). We already had support for &&, ||, ^^ but somehow the common cases of == and != were not implemented in the constant-folder. This CL also updates the test to return a green/red color on success or failure, instead of assigning arbitrary numbers into sk_FragColor that don't mean anything. The long-term plan is to signal success or failure of each test by color code; we can display these colors as swatches in a GM slide for testing purposes.

Allow compile-time intrinsic evaluation to read const variables. Previously, the code neglected to resolve constant variables into values. This meant that expressions like `lessThan(zero, one)` could not be compile-time evaluated even when `zero` and `one` have known values.

Convert several SkSL->GLSL unit tests to golden outputs. The new test files are intended to be identical to the unit tests in every meaningful way. (Comments and formatting are not preserved exactly.) In cases where a unit-test method contained more than one test, multiple test files were created; in these cases, new names were invented to match the apparent intent of each invocation. Followup CLs will continue to migrate additional tests.

Update folding tests to return pass/fail status. A passing test returns solid green. Failing tests are written to return solid red, but drawing any other color than green can be interpreted as a test failure. Additionally, tests which cannot compile as RuntimeEffects (due to non-ES2-compatible features) have been split into an ES2-compatible part and an ES3 part.
