Got some details on how much this costs? (eg: `bloaty` comparison for a clang 
bootstrap with/without this patch applied?)
Could you provide a quick summary of why this debug info is required? The 
definition should be provided in whatever translation unit defines the variable 
and you should be able to get debug info from there - if that translation unit 
is built without -g, then maybe this feature should be gated on 
`-fstandalone-debug` which is intended to express the intent to get debug info 
coverage when a translation unit may be the only one built with `-g`?
