912a7acc1e Add FunctionArgApplyInfo::getArgDescription 
This commit adds a member which produces a string
describing the argument being applied. This will
either be its argument label or position in the
argument list.

7077a68b83 [Sema] Diagnose unsound pointer conversions 
Diagnose ephemeral conversions that are passed to @_nonEphemeral
parameters. Currently, this defaults to a warning with a frontend flag
to upgrade to an error. Hopefully this will become an error by default
in a future language version.

3e1a61f425 [NFC] Fold The Tri-State In Optional<ProtocolConformanceRef> 
ProtocolConformanceRef already has an invalid state.  Drop all of the
uses of Optional<ProtocolConformanceRef> and just use
ProtocolConformanceRef::forInvalid() to represent it.  Mechanically
translate all of the callers and callsites to use this new
representation.

d90117bb8a [Diagnostics] Remove argument handling from conformance failures 
Argument-to-Parameter mismatch handles conformance failures
related to arguments, so the logic in `MissingConformanceFailure`
which wasn't entirely correct is now completely obsolete.
