Doug Gregor 453277eb74 Mark the various with* functions as @safe 
Functions like withUnsafeBufferPointer are, by themselves, safe to
call. It's only the operations on the unsafe pointers passed into the
closure that are the safety issue.

This was the intent spelled out in SE-0458 but was not fully realized
in the library.

Fixes rdar://174519372.

Gabor Horvath 402ad33463 [StrictMemorySafety] Check the safety of return types of calls 
Previously, we skipped checking the return type of a function for safety
as we expected to warn at the use of the returned value:

  let x = returnsUnsafe()
  usesUnsafe(x) // warn here

Unfortunately, this resulted in missing some unsafe constructs that can
introduce memory safety issues when the use of the return value had a
different shape resulting in false negatives for cases like:

  return returnsUnsafe()

or

  usesUnsafe(returnsUnsafe())

This PR changes the analysis to always take return types of function
calls into account.

Konrad `ktoso` Malawski 8a88569c6b [Distributed] remoteCallVoid is a new requirement in Swift 6.0 
And it is handled compatibly because all existing implementations must
have already implemented it before -- it was an ad-hoc requirement
before Swift 6.0, and now it has become a real requirement - the same as
all the other ad-hoc requirements relying on the Serialization
Requirement
