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.

2cedf1c86a [ClangImporter] Bulk up some comments per Graydon's feedback. (#15780) 
DavidU would probably say this function needs to be split up more too,
and he wouldn't be wrong, but that's a bigger change. (The original
change is getting cherry-picked.)

d20bcf14c2 [Type checker] Prefer available declarations in AnyObject lookup. 
When we perform AnyObject lookup, we can find multiple declarations with
the same signature. When we do so, we pick fairly arbitrarily among them.
However, make sure that we don’t pick an unavailable declaration when
an available declaration is… available.

Fixes rdar://problem/39115471.

c3fc74e10c [ClangImporter] Honor -Xcc -W* flags for en/disabling Clang warnings (#15771) 
Previously we set up the diagnostic options too early for these flags
to be honored, in order to diagnose problems in parsing the arguments
being passed to Clang. The solution is to decide that that diagnostic
engine is a temporary one and to create a proper one later. (And if
this sounds like a lousy solution, I don't disagree, but it's what
Clang does too.)

daa094e5e0 [Coverage] Only instrument functions which are definitions 
The ASTs for functions which aren't definitions may not be fully
typechecked or well-formed, so: avoid looking at them.

This fixes at least one assertion failure seen while building a project
with coverage, and is probably good for some substantial compile-time
improvements with coverage enabled.
