This revives Alessandro Arzilli's CL to enable scopes whenever any dwarf is emitted (with optimization or not), adds a test that detects this changes and shows that it creates more truthful debugging output. Reverted change to ssa/debug_test tests made when scopes were disabled during dwarflocationlist development. Also included are updates to the Delve test output (it had fallen out of sync; creating test output for one updates it for all) and minor naming changes in ssa/debug_test.
