Don't claim a fat IR object if no IR object should be claimed
When the linker sees an input object containing nothing but IR during
rescan, it should ignore it (LTO phase is over). But if the input object
is a fat IR object, which has non-IR code as well, it should be used to
resolve references as if it did not contain any IR at all. This patch
adds lto_type to bfd and linker avoids claiming a fat IR object if no IR
object should be claimed.
