a7e6e9a1 - [4.2] SIL: Profile the witnessMethodConformance as part of the SILFunctionType

[4.2] SIL: Profile the witnessMethodConformance as part of the SILFunctionType We use to return a SILFunctionType with a wrong witness method protocol conformance e.g when there were base protocols. Scope: We would end up with wrong protocol conformances in SIL function types. Any consumer that relies on their correctness could fail Risk: Low – it seems so far no one has discovered that hey where wrong in the first place. Testing: Normal test suite.
