Simplify inlining now that the scheduler is smart(er).

* Only control adjustment is to move everything from the inlinee's
  start block to the block the call was in.
* Add a unit test to ensure that the scheduler actually picks the
  right order when placing the code.

Add MachineSignature, which is an encapsulation of the machine types for parameters and return values in a graph.

This utility will be used to simplify Linkage and fix representation inference
to work with graphs where parameters and return values are something other
than tagged. It will also make testing representation inference a lot
easier, since we can then exactly nail down the machine types of parameters
and returns.

This CL also adds c-signature.h, which demonstrates how to convert C function
signatures into MachineSignatures. The CSignatures will be used in tests to
make it easier and simpler to codegen tests.

Note: The test failure was unrelated to the fact that it run on actual
