%TypedArray%.prototype.lastIndexOf ( searchElement [ , fromIndex ] )
%TypedArray%.prototype.lastIndexOf is a distinct function that implements
the same algorithm as Array.prototype.lastIndexOf as defined in 22.1.3.17
except that the this value's [[ArrayLength]] internal slot is accessed
in place of performing a [[Get]] of "length".
Array.prototype.lastIndexOf ( searchElement [ , fromIndex ] )
[...]
8. Return -1.
