ISSUE(tc39/ecma262#938): {{HostEnsureCanCompileStrings()}} does not include the string which is
going to be compiled as a parameter. We'll also need to update HTML to pipe that value through
to CSP.
Note: |parameterStrings|, |bodyString|, |compilationType|, |parameterArgs|, and |bodyArg| are currently unused. They are included for future use.
