### Compilation failed:

error: 3: discard statement is only permitted in fragment shaders
error: 5: do-while loops are not supported
error: 7: while loops are not supported
3 errors
Move all runtime effect error tests to runtime_errors Also renamed Discard to IllegalStatements, and added testing of while and do loops.

Implement switch in SkVM. 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).
