    readdwarf3.c (parse_inl_DIE) inlined_subroutine can appear in namespaces
    
    This was broken by commit 75e3ef0f3 "readdwarf3: Skip units without
    addresses when looking for inlined functions". Specifically by this
    part: "Also use skip_DIE instead of read_DIE when not parsing
    (skipping) children"
    
    rustc puts concrete function instances in namespaces (which is
    allowed in DWARF since there is no strict separation between type
    declarations and program scope entries in a DIE tree), the inline
    parser didn't expect this and so skipped any DIE under a namespace
    entry. This wasn't an issue before because "skipping" a DIE tree was
    done by reading it, so it wasn't actually skipped. But now that we
    really skip the DIE (sub)tree (which is faster than actually parsing
    it) some entries were missed in the rustc case.
