Summary CodeBlock::shrinkToFit is racy

Reported 2016-06-21 11:29:26 PDT
Let's say CodeBlock A is finalizing its baseline compile. Let's say CodeBlock B is inlining A, and asks A for a result profile. This happens as the finalizing step of the baseline compile calls shrinkToFit on its m_resultProfiles field without grabbing lock. This leads to a bad time.
