Merge #7506
7506: Use block_def_map in body lowering r=jonas-schievink a=jonas-schievink This makes `lower_block` update the `DefMap` and `ModuleId` used by the expander to the corresponding `block_def_map`. This cleans up a bit of code, but doesn't expose any new features. bors r+ Co-authored-by: Jonas Schievink <[email protected]>
