The code is also ia64 specific. I don't have any objections to putting
it under ia64.

That dir is for C++ ABI support. We shouldn't move it there.

Re: common

There is also a dir called "mi" (machine independent). But this is
arch specific code, so we shouldn't move it there.

If runtime dependency between different components of libunwind*.a is
a concern, you can statically link object files into
libunwind-coredump.a with some Makefile hackery.
