## Message

```
AstGen: improve switch expressions

 * use the proper result location strategy even when there are noreturn
   prongs in the switch expression
 * when using break_operand strategy, actually omit the
   store_to_block_ptr instructions rather than eliding them.
 * for both strategies, properly handle noreturn prongs.

```
