[dsymutil] Add support for mergeable libraries
This adds support in dsymutil for mergeable libraries [1].
dsymutil reads a new stab emitted by ld, allowing it to operate on
dynamic libraries instead of object files. It also now loads the DWARF
files associated to the libraries, and build the debug map for each
binary from the list of symbols exported by the library. For each Debug
Map Object, there is a new associated Relocation Map which is serialized
from the information retrieved in the original debug_info (or
debug_addr) section of the .o file.
The final DWARF file has multiple compile units, so the offsets
information of the relocations are adjusted relatively to the compile
unit they will end up belonging to, inside the final linked DWARF file.
