Auto merge of #45316 - goffrie:exitable-breakable-block, r=nikomatsakis

Mark block exits as reachable if the block can break.

This only happens when desugaring `catch` expressions for now, but regular blocks (in HIR) can be broken from - respect that when doing reachability analysis.

Fixes #45124.
