description: Templates are cached by source location inside a function
info: >
    Each time eval is called, it is a different site. However, a loop within
    the eval is considered the same site. This is a regression test for an
    issue that Caitlin Potter faced in implementations of the new template
    caching semantics in both V8 and JSC.

    1. For each element _e_ of _templateRegistry_, do
      1. If _e_.[[Site]] is the same Parse Node as _templateLiteral_, then
        1. Return _e_.[[Array]].
