and lexical scopes, which can be enabled through the new -g option. When -g is enabled, line tables and scopes compile all the way down to DWARF. Changes to SIL: - In addition to a SILLocation, every instruction now also has a pointer to a SILDebugScope (its containing lexical scope). - Added LexicalScope, which is to be used for all Scopes we want to show up in the debug info.
