If EscapeAnalysis verification runs on unreachable code, it asserts with "Missing escape connection graph mapping" because the connection graph builder only runs on reachable blocks. Add a ReachableBlocks utility and use it during verification. Fixes <rdar://problem/60373501> EscapeAnalysis crashes with CFG with unreachable blocks
