    Libdw: Add libdw-based stack unwinding · a6a3dabc
    Ben Gamari authored
    This adds basic support to the RTS for DWARF-assisted unwinding of the
    Haskell and C stack via libdw. This only adds the infrastructure;
    consumers of this functionality will be introduced in future diffs.
    
    Currently we are carrying the initial register collection code in
    Libdw.c but this will eventually make its way upstream to libdw.
    
    Test Plan: See future patches
