commit 152a11e05d993c6cfd77422599ec6973b838ca9a
Author: Mark Wielaard <mjw@redhat.com>

    unwind.c fde_pointer_type fix (fake) 'P' encoding type value reading.
    
    We are not actually interested in the personality routine value,
    so don't try to deref (which will usually fail). Mask off DW_EH_PE_indirect.

    runtime/unwind split fde/cie parsing.
    
    Split parsing/sanity checking of fde and cie. This removes the bad_cie
    and not_fde statics. is_fde will just return NULL and produce a warning.

    unwind.c Only do a linear search if there isn't a search header.
    
    There always should be one, we create it in the translator
    if it didn't exist. Only if we are using elfutils < 0.142
    should these ever be missing. If the binary search fails,
    either because the unwind data is bad, or the address isn't
    covered, don't fall back to linear searching. Add extra
    checks and warning about bad debug frame header.
