Slava Pestov 435d66f70b Sema: Add separate pass for checkConformancesInContext()

I tried doing this directly from typeCheckDecl(), but it breaks
associated type inference. We can figure this out later when
declaration checking becomes lazier and more incremental.

Note that typo correction does not force witnesses of
synthesized conformances. This means that a typo correction
from a top-level form will no longer pick up synthesized
witnesses, and will find the protocol requirement instead.

To give a test the same behavior as before, I put the
expression in a function body instead of a top-level form.

Note that we already had the same behavior with typo
correction from pattern binding initializers and other
contexts that are type checked before conformances.
