        enum ubsan_encode_value_phase with default value of
        UBSAN_ENCODE_VALUE_GENERIC.
        * ubsan.c (ubsan_encode_value): Change second argument to
        enum ubsan_encode_value_phase PHASE from bool IN_EXPAND_P,
        adjust uses, for UBSAN_ENCODE_VALUE_GENERIC use just
        create_tmp_var_raw instead of create_tmp_var and use a
        TARGET_EXPR.

        instrument_bool_enum_load, ubsan_instrument_float_cast): Adjust
