Kevin Enderby ac9e15551d Change llvm-objdump, llvm-nm and llvm-size when reporting an object file error
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.

Peter Collingbourne bc05163f15 LibDriver, llvm-lib: introduce.
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.

David Majnemer c7d7c6fb3a Object, COFF: Cleanup symbol type code, improve binutils compatibility
Do a better job classifying symbols.  This increases the consistency
between the COFF handling code and the ELF side of things.

Kevin Enderby 08e1bbd645 Add an implementation for llvm-nm’s -print-file-name option (aka -o and -A).
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.

Kevin Enderby 8da4bd60fb Changed the lvm-nm alias "-s" for -print-armap to "-M".
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.

Rafael Espindola 95cf2f25fe Fix pr17056.
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.

Alp Toker f907b891da Correct word hyphenations
This patch tries to avoid unrelated changes other than fixing a few
hyphen-related ambiguities and contractions in nearby lines.

Rafael Espindola 555aa899c6 Remove this test for now.
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).

Should fix the bots that are seeing a corrupted file from a previous run.
