YAML profile reader checks the number of basic blocks in regular,
no-stale-matching mode. Add it to BAT.

This increases the size of BAT section to:
- large binary: 39583080 bytes (1.02x of the original),
- medium binary: 3816492 bytes (0.64x),
- small binary: 920 bytes (0.64x, no change due to alignment).

Test Plan: Updated bolt-address-translation-yaml.test
