Summary: Extends the multivalue call infrastructure to tail calls, removes all legacy calls specialized for particular result types, and removes the CallIndirectFixup pass, since all indirect call arguments are now fixed up directly in the post-insertion hook. In order to keep supporting pretty-printed defs and uses in test expectations, MCInstLower now inserts an immediate containing the number of defs for each call and call_indirect. The InstPrinter is updated to query this immediate if it is present and determine which MCOperands are defs and uses accordingly. Depends on D72902.
