## Message

```
astgen: const locals that end up being rvalues do not alloc

Local variable declarations now detect whether the result location for the
initialization expression consumes the result location as a pointer. If
it does, then the local is emitted as a LocalPtr. Otherwise it is
emitted as a LocalVal.

This results in clean, straightforward ZIR code for semantic analysis.
