di_notify_ACHIEVE_ACCEPT_STATE: before starting to parse the ELF file,
truncate overlaps in the DebugInfoMappings that have been collected by
the DebugInfo's FSM.  Not doing so can confuse ML_(read_elf_debug_info)'s
computation of bias values.  Observed to be a problem when reading EDIDX
sections for objects mangled by Mike Hommey's elfhack program.
