Add int-vector folding tests to VectorFolding. This test is meant to demonstrate that constant folding for int and float vectors is not on equal footing. Float vectors currently generate better-optimized output.

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.

Add fix for fuzzer-discovered crash with negated constructors. This was found at https://oss-fuzz.com/testcase-detail/5155684475469824 but the associated oss-fuzz issue ID appears to be misdirected (it's showing oss-fuzz:24498, an unrelated issue). PrefixExpressions can return true for `isCompileTimeConstant` but did not implement `compareConstant`; the fuzzer discovered this. Because compile-time constants can only be compared if they are of the same kind, this means that `compareConstant` is actually comparing a pair of expressions that are both negated. These negations will just cancel out, so `compareConstant` on a pair of PrefixExpressions can just call `compareConstant` on the inner operand of each expression.
