Rafael Espindola 449208d95b Handle the error of trying to convert a regular archive to a thin one.
While at it, test that we can add to a thin archive.

Rafael Espindola 594e676cbe llvm-ar: Pad the symbol table to 4 bytes.
It looks like ld64 requires it. With this we seem to be able to bootstrap using
llvm-ar+/usr/bin/true instead of ar+ranlib (currently on stage2).

Rafael Espindola c79bff6bb1 Basic support for BSD symbol tables in archives.
This could be optimized and for now we only produce __.SYMDEF
and not "__.SYMDEF SORTED".

Rafael Espindola 2ba806c702 Remove redundant variable. NFC.

Rafael Espindola b870e9ca93 Add a helper to printing BE of LE depending on the format.
The gnu ar format uses BE numbers. The BSD one uses LE. Add a helper for one or the
other. NFC for now, just removes some noise from the following patch.

Rafael Espindola 8cde5c01d8 Extract printBSDMemberHeader.
It will get another use in the following patch. Also rename the other helper to
printGNUSmallMemberHeader for consistency.

Rafael Espindola c91177e410 Disallow Archive::child_iterator that don't point to an archive.
NFC, just less error prone.

Rafael Espindola a2ed0b0bab Start adding support for writing archives in BSD format.
No support for the symbol table yet (but will hopefully add it today).
We always use the long filename format so that we can align the member,
which is an advantage of the BSD format.

Rafael Espindola 74f293249d Don't use std::errc.
As noted on Errc.h:

// * std::errc is just marked with is_error_condition_enum. This means that
//   common patters like AnErrorCode == errc::no_such_file_or_directory take
//   4 virtual calls instead of two comparisons.

And on some libstdc++ those virtual functions conclude that

------------------------
int main() {
  std::error_code foo = std::make_error_code(std::errc::no_such_file_or_directory);
  return foo == std::errc::no_such_file_or_directory;
}
-------------------------

should exit with 0.

diagnostics.
