Passing less number of arguments to a function is generally faster. So

the three boolean arguments of ecma_create_named_data_property and the
two boolean arguments of ecma_create_named_accessor_property are combined
into one uint8_t argument. On ARM-32 it is preferred to have less than
four arguments, since these arguments can be passed in registers.
