Summary: A block address may be used in inline assembly. In which case it requires a name so that the asm parser has something to parse. Creating a name for every block address is a large hammer, but is necessary because at the point when a temp symbol is created we don't necessarily know if it's used in inline asm. This ensures that it exists regardless.
