when the object is in an archive to use something like libx.a(foo.o) as part of
the error message.
Also changed llvm-objdump and llvm-size to be like llvm-nm and ignore non-object
files in archives and not produce any error message.
To do this Archive::Child::getAsBinary() was changed from ErrorOr<...> to
Expected<...> then that was threaded up to its users.
Converting this interface to Expected<> from ErrorOr<> does involve
touching a number of places. To contain the changes for now the use of
errorToErrorCode() is still used in one place yet to be fully converted.
Again there some were bugs in the existing code that did not deal with the
old ErrorOr<> return values. So now with Expected<> since they must be
checked and the error handled, I added a TODO and a comments for those.

llvm-lib is intended to be a lib.exe compatible utility that also
understands bitcode. The implementation lives in a library so that
lld can use it to implement /lib.

The -print-file-name option in llvm-nm is to precede each symbol
with the object file it came from. While code for the parsing of this
option and its aliases existed there was no code to implement it.

This will allow the "-s" flag to implemented in the future as it
is in darwin’s nm(1) to list symbols only in the specified section.
Given a LGTM by Shankar Easwaran who originally implemented
the support for lvm-nm’s -print-armap and archive map symbols.

This makes llvm-nm ignore members that are not sufficiently aligned for
lib/Object to handle.
These archives are invalid. GNU AR is able to handle this, but in general
just warns about broken archive members.
We should probably start warning too, but for now just make sure llvm-nm
exits with an 0.

It is not reliable to depend on the output of llvm_unreachable. The original
change will have proper tests when llvm-ar moves to lib/Object (soon).
