[Interpreter] Add support for Call bytecode to bytecode graph builder.

[Interpreter] Add support for Call bytecode to bytecode graph builder.

Adds support for visiting the Call bytecode to the bytecode graph builder.
This change also adds the call type feedback slot to the Call bytecode.
This is not currently used by the interpreter, but is used by the
graph builder.

Also adds a CallWide varient of the Call bytecode, and adds the kCount16
operand type.

Landed on behalf of rmcilroy.

This CL is based on Ross's CL https://codereview.chromium.org/1437873002/ that
I'm attempting to land in his absence. You've already LGTM'ed it so it should be
a quick review. Just a couple of minor changes (spelling and a sign-unsigned
compilation fix). 

Thanks!

LGTM (you can also TBR CLs if you're just landing them for Ross and we already
LGTMed the original CL).
