This option outputs the location, encoded value and target of chained
fixups, using the same format as `otool -dyld_info`.

This initial implementation only supports the DYLD_CHAINED_PTR_64 and
DYLD_CHAINED_PTR_64_OFFSET pointer encodings, which are used in x86_64
and arm64 userspace binaries.

When Apple's effort to upstream their chained fixups code continues,
we'll replace this code with the then-upstreamed code. But we need
something in the meantime for testing ld64.lld's chained fixups code.
