### Compilation failed:

error: 3: static switch contains non-static conditional exit
void test_break()    { @switch (1) { case 1: if (testInputs.x > 2) break; } }

Fix switch optimization pass. The optimizer now properly recognizes all types of exits from a switch statement. Break, continue and return are all potential exits and need to be considered when determining the exit path from the switch. Previously, dead code elimination was hiding the effects of this bug from us, but it meant that an optimized switch had the potential to generate lots of worthless IR nodes which then needed to be detected and eliminated by the CFG. In particular, this affected the enum form of blend, causing a catastrophic amount of extra work to be done.

Added range highlighting to SkSL error reports SkSL errors now identify the specific range of code they are describing, rather than just the line number.
