  [JSC] uDFG should be able to watch JSGlobalObject WatchpointSets

Reviewed by Mark Lam.

This patch allows uDFG to watch JSGlobalObject WatchpointSets.
We extract this watchpoint insertion as a LinkerIR. And we run this when materializing DFG::JITData,
which should eventually become uDFG's linking phase. We also fixed a bug where we missed visiting
uDFG CallLinkInfo in CodeBlock.
