[JSC] Concurrently computing CodeBlockHash
https://bugs.webkit.org/show_bug.cgi?id=295000
rdar://154307835
Reviewed by Yijia Huang.
This patch fixes an issue for concurrent CodeBlockHash. We put some
locks around CachedScriptSourceProvider / ScriptBufferSourceProvider
to ensure that we can touch these source code safely (do not ref them.
This is concurrently touched).
