 418         Created new kGroupSubordinate reference kind to model group comdat.  The "signature" atom
 419         has kGroupSubordinate references to the other atoms in the group.  If the signature atom
 420         is coalesced away, the linker follows kGroupSubordinate references and throws away the
 421         other members of the group.
 422         * unit-tests/test-cases/eh-coalescing: added test case
 423         * src/ld.cpp: added markDead() and use propagate to subordinates
 424         * src/Architectures.hpp: added kGroupSubordinate
 425         * src/MachOReaderRelocatable.hpp: add kGroupSubordinate reference from a function to its .eh atom
 426           and if used, from .eh atom to its LSDA atom.
