linux, dump_syms: Filter module entries outside specified ranges
Partitioned libraries generated with lld and llvm-objcopy currently contain a superset of debug information, beyond what applies to the library itself. This is because objcopy cannot split up debug information by partition - instead, it places a copy of all debug information into each partition. In lieu of potential future support for lld or objcopy becoming able to split up debug information, let dump_syms do the next best thing: - Find the address ranges of all PT_LOAD segments in the lib. - Supply these to the Module being generated. - Filter additions to the Module based on these ranges.
