The base implementation of `_.indexOf` without support for binary searches
or `fromIndex` constraints.

@private
@param {Array} array The array to search.
@param {*} value The value to search for.
@param {number} [fromIndex=0] The index to search from.
@returns {number} Returns the index of the matched value or `-1`.
