! Test that .cranges are emitted:
!  1) Not for sections with single contents.
!  2) For data (through pseudo-ops) in SHmedia.
!  3) For mixed SHcompact and SHmedia sections.
!  4) For a mix of 2 and 3
!  5) For 4, repeated.
!
! Use section contents that need relaxing to strengthen the check that the
! .cranges implementation handles this correctly.  Use different sizes for
! each contents part.
!
 
! The .text section has only SHmedia contents, and should not get a
! .cranges descriptor.
