`-Z debug-macros` is "stabilized" by enabling it by default and removing. `-Z collapse-macro-debuginfo` is stabilized as `-C collapse-macro-debuginfo`. It now supports all typical boolean values (`parse_opt_bool`) in addition to just yes/no. Default value of `collapse_debuginfo` was changed from `false` to `external` (i.e. collapsed if external, not collapsed if local). `#[collapse_debuginfo]` attribute without a value is no longer supported to avoid guessing the default.
