Why?

You don't want to merge the types in the debuginfo.

You only have to parse the debuginfo types that correspond to types
you've changed in some fashion
(and if you don't want to do that you only have to parse to update the
variable info, which means you don't even have to parse or follow the
DW_AT_type references)
