At IR generation time, this CL limits our optimizations to only @switch statements. A regular switch statement will only be optimized during the optimization phase even if the switch-value is a known compile-time constant. This is done to avoid upsetting our reachability analysis. Most of this CL is moving existing logic from SkSLCompiler into SkSLAnalysis and SkSLSwitchStatement. Although the diffs look large, the actual changes are very small.
