CallLinkStatus should be aware of closure calls, and the DFG bytecode parser should use that as its sole internal notion of how to optimize calls

Previously, the DFG bytecode parser had its own internal notion of exactly what CallLinkStatus was
meant to do, in the form of a CallType, expectedFunction, intrinsic, etc. This change makes CallLinkStatus
smart enough to do all of that, and also gives it the ability to understand closure calls.

I got tired of the various idioms for printing a list of things with comma in between, so I wrote a helper.
