llvm-ar: be more clever about default format
Try to be more clever about selecting the default format. When an existing
archive is used, use the type of the archive to determine the format. When
existing members are present, use the first member's format to determine the
format to use. If we are creating an empty archive (MRI mode) or are adding
non-object members, default to the current behaviour of using the host type due
to the lack of a better alternative. This aids in cross-compilation on Darwin
to non-Darwin platforms which rely on GNU format archives.
