Meta-program setupArguments and callOperation
https://bugs.webkit.org/show_bug.cgi?id=183263

Rubber-stamped by Filip Pizlo.

Source/JavaScriptCore:

This patch removes all the custom overrides of callOperation and setupArguments
throughout the JITs. In their place there is a new setupArguments that marshalls
the arguments into place based on the type of the operation's function pointer.
There were a couple of design choices in the implementation of setupArguments:

1) We assume that no TrustedImm floating point values are passed.
2) If ExecState* is the first argument the callFrameRegister should be marshalled implicitly.
3) Types should not be implicitly converted (with the exception of DFG::RegisteredStructure -> Structure*)

The new callOperation/setupArguments do their best to make sure
it's hard to call a function with the wrong parameters. They will
only try to pattern match if the types match up with the next
passed argument. Additionally, the base case should static_assert
of the number of inferred arguments does not match the arity of
the operation's function pointer.

Add a new function traits struct that provides interesting
information about the provided function pointer. Right now it only
provides information for function pointers, in theory we could
also get it to work for other types.
