PerformEval should be modified to use xStr for the rest of the algorithm

[fred-wang]

See https://tc39.es/proposal-dynamic-code-brand-checks/#sec-performeval
We determine a xStr value that we use for HostEnsureCanCompileStrings.

However, the x value is also used at step 11)a) of https://tc39.es/ecma262/#sec-performeval

Let script be ParseText(x, Script).

I assume the intention is to use xStr here too?

That's what tc39/ecma262#3294 does, so answer is yes.
