Log:
  MFC r296419 (by kib):

  In the link_elf_obj.c, handle sections of type SHT_AMD64_UNWIND same
  as SHT_PROGBITS.  This is needed after the clang 3.8 import, which
  generates that type for .eh_frame section, which had SHT_PROGBITS type
  before.

  MFC r296428:

  Since kernel modules can now contain sections of type SHT_AMD64_UNWIND,
  the boot loader should not skip over these anymore while loading images.
  Otherwise the kernel can still panic when it doesn't find the .eh_frame
  section belonging to the .rela.eh_frame section.

  Unfortunately this will require installing boot loaders from sys/boot
  before attempting to boot with a new kernel.
