22.2.3.13 %TypedArray%.prototype.indexOf (searchElement [ , fromIndex ] )
%TypedArray%.prototype.indexOf is a distinct function that implements the same
algorithm as Array.prototype.indexOf as defined in 22.1.3.12 except that the
this object's [[ArrayLength]] internal slot is accessed in place of performing
a [[Get]] of "length".

a. If n is -0, let k be +0; else let k be n.
