Log:
    PR debug/50299
    * calls.c (load_register_parameters): Use use_reg_mode instead
    of use_reg when adding a single register CALL_INSN_FUNCTION_USAGE
    entry.
    (expand_call): Set EXPR_LIST mode to TYPE_MODE of the argument
    for stack CALL_INSN_FUNCTION_USAGE uses.
    * expr.h (use_reg_mode): New prototype.
    (use_reg): Changed into inline around use_reg_mode.
    * expr.c (use_reg): Renamed to...
    (use_reg_mode): ... this.  Added MODE argument, set EXPR_LIST
    mode to that mode instead of VOIDmode.
    * var-tracking.c (prepare_call_arguments): Don't track parameters
    whose EXPR_LIST mode is VOIDmode, BLKmode or X mode isn't convertible
    to it using lowpart_subreg.  Convert VALUE and REG/MEM to the
    EXPR_LIST mode.
