This is a reland off5d30c90efChanges from original CL: moved fuchisa libunwind dependency back into libc++abi. [1] removed the need to build libc++abi with libunwind, so libunwind was removed on the Linux config after that CL. However, an unwinder is still necessary for libc++abi to build, whether it's provided by glibc or libunwind or whatever. But I mistakenly thought the dependency on an unwinder in general was removed, so I added a bad TODO to move libunwind up to common_deps. Fuchsia's libc doesn't provide an unwinder, so the libunwind dependency is still necessary. This CL simply removes the TODO and adds only the visibility changes from the original CL.
