commit d4af357ee2b163b6ba3d7454ae97a52b0124edb8
Author: Mark Wielaard <mjw@redhat.com>

    Handle CIE and FDE CFI sequentially in unwind.c instead of recursively.
    
    Another simple unwind.c cleanup to make reasoning about the unwind state
    easier, and to remove another (useless) recursive call. Also fixes CIE/FDE
    comment mixup.

commit f24522b449897a092e5a7e87a805e0bdd3898724

    Refactor DW_CFA_remember/restore_state handling in unwind.c.
    
    The old way of handling DW_CFA_restore_state involved recursively
    calling processCFI() to replay the whole CFI stream up till the last
    DW_CFA_remember_state instruction. This made it hard to reason about
    the actual unwind state and could lead to processing the CFI stream
    multiple times. In exchange for a little extra memory allocated upfront
    to keep a small stack of register states we now just process all CFI in
    one go. This change also splits out the unwind_reg_state from the
    general unwind_state struct.
