Log:

        * cfgexpand.c (expand_debug_expr): Handle CONJ_EXPR.
        * dwarf2out.c (mem_loc_descriptor): Don't handle
        POST_INT/POST_DEC/POST_MODIFY like SUBREG.  For SUBREG
        punt if it is not lowpart subreg or if inner mode isn't
        MODE_INT.

        * gcc.dg/debug/pr41717.c: New test.
