ed1cd46d25 [ownership] Update devirtualization utilities for ownership. 
I discovered this due to the mandatory inliner doing devirtualization. I ported
all of the relevant SIL tests to increase code coverage of this code when
ownership is enabled.

fd4828e40a Eliminate -assume-parsing-unqualified-ownership-sil from tests. 
I am doing this separately from the actual change to eliminate the option to
make it easier to review.

ca67b43bf2 SIL: Print the '@' prefix for function names in sil_vtables. 
This is needed for supporting $-prefixed SIL names and it's also consistent with the witness table syntax.

8ddbb6891c SIL: Remove superclass walk from SILModule::lookUpFunctionInVTable() 
Note that I had to update a SIL optimizer test after making this
change. The old test was basically meaningless because the SIL
was malformed.

bf2dcbf25e Use function signatures for SILDeclRefs in witness_tables, vtables and witness_method instructions. 
Textual SIL was sometimes ambiguous when SILDeclRefs were used, because the textual representation of SILDeclRefs was the same for functions that have the same name, but different signatures.

7d594fb60d [sil-devirtualizer] Use a more advanced algorithm to figure out the exact types of instances 
- Look through BB arguments with multiple predecessors.
- Provide a new helper function to figure out the exact type of the underlying object. It will be used by subsequent commits to improve the escape analysis.

70938b1aee Add a stand-alone devirtualizer pass. 
Add back a stand-alone devirtualizer pass, running prior to generic
specialization. As with the stand-alone generic specializer pass, this
may add functions to the pass manager's work list.

This is another step in unbundling these passes from the performance
inliner.
