SkVM implements switches as a pseudo-loop; breaks are handled with the condition mask just like a for loop. Fallthrough is handled via a scratch Value in a temporary slot. `writeStore` neeeded to be refactored to support writing into slot(s) without an associated Variable. At IR generation time, SwitchStatements are now emitted without error even in strict-ES2 mode. The GLSL code generator currently reports these as an error in strict-ES2 mode, but this will be fixed in a followup coming shortly (the switch will be rewritten as ifs inside a one-shot loop, similar to our IR-rewrite strategy).
