The base implementation of `_.indexOf` without `fromIndex` bounds checks.

@private
@param {Array} array The array to inspect.
@param {*} value The value to search for.
@param {number} fromIndex The index to search from.
@returns {number} Returns the index of the matched value, else `-1`.
function baseIndexOf(array, value, fromIndex) {
	  if (value !== value) {
	    return baseFindIndex(array, baseIsNaN, fromIndex);
	  }
	  var index = fromIndex - 1,
	      length = array.length;

	  while (++index < length) {
	    if (array[index] === value) {
	      return index;
	    }
	  }
	  return -1;
	}
