bfd865b6b6 [ApplySite] Renamed insertAfterApplication. 
Now that it can be called on partial_apply instructions,
insertAfterFullEvaluation does not name what the function does.  One
could imagine a function which inserted after the applies of
(non-escaping) partial_applies.

38779f32c1 SILGen/IRGen: Delegate decision to skip @_silgen_name functions to TBDGenVisitor. 
This allows SILGen for `#_hasSymbol` conditions to visit them and emit a declaration of the function appropriately.

332750d1fd [SILGen] Handle @out tuple expansion. 
When branching to the exit block, flatten an @out tuple return value
into its components, as is done for all other return values.

In the exit block, when constructing the @out tuple to return, visit the
tuple-type-tree of the return value to reconstruct the nested tuple
structure: @out tuple returns are not flattened, unlike regular tuple
returns.

Previously the API was only on FullApplySite, but it is useful to be
able to insert code after a partial_apply as well.

f5d760e613 Interop: Untangle circular dependency introduced by #59787 
The changes for https://github.com/apple/swift/pull/59787 introduced a circular depenendcy between the SIL library and the SILGen library. I have undone this in the cheapest way possible as I don't have bandwidth to look into a more correct fix at the moment.

f98917b1fe Removed workaround for missing Swift sources. 
Previously, to workaround an issue with ShrinkBorrowScope (where it
assumed a reasonable definition of isDeinitBarrier), a placeholder
version of the function was added.  It is now removed by moving the
implementation of a version of that predicate back to C++.

ecbcacdecf SIL Analysis: Rename InvalidationKind::FunctionData to InvalidationKind::Effects

Also, let optimization passes which don't change effects only invalidate the `FunctionBody` and not `Everything`.

7ea336367d [NFC] Port isDeinitBarrier to Swift. 
Added new C++-to-Swift callback for isDeinitBarrier.

And pass it CalleeAnalysis so it can depend on function effects.  For
now, the argument is ignored.  And, all callers just pass nullptr.

Promoted to API the mayAccessPointer component predicate of
isDeinitBarrier which needs to remain in C++.  That predicate will also
depends on function effects.  For that reason, it too is now passed a
BasicCalleeAnalysis and is moved into SILOptimizer.

Also, added more conservative versions of isDeinitBarrier and
maySynchronize which will never consider side-effects.

ab35362056 [SIL] Added new test_specification instruction. 
The new instruction exists only to be used in tests.  The idea is to

function.
