Pull Request Overview
This PR fixes a bug in the JIT compiler's cast type checking logic when dealing with address casts. The issue was that the code was incorrectly checking the node's type instead of the cast's target type when filtering out casts of local addresses to small types.
- Replaces direct type checking with proper cast target type validation
- Adds proper code block structure around the GT_CAST case
- Fixes the logic to correctly identify pointer-type casts

The failing test in #118006 casts addresses of locals to small types, and this check was not checking the right type to filter out those casts.
