    debug/92763 keep DIEs that might be used in DW_TAG_inlined_subroutine

    We were pruning type-local subroutine DIEs if their context is unused
    despite us later needing those DIEs as abstract origins for inlines.
    The patch makes code already present for -fvar-tracking-assignments
    unconditional.
