8d180f4bdc [SILDiagnostics] Add suppression for swap() to static access enforcement. 
Add a SILLocation-based syntactic suppression for diagnostics of static
access conflicts on the arguments to the Standard Library's swap() free
function. We'll suppress for calls to this function until we have a safe
replacement.

fff80ba77c [Exclusivity] Fix Definite Initialization for Diagnostics. 
Handle mutating methods in initializers properly.

This only affects --enforce-exclusivity mode.
It will be unit tested by default soon.

8aa9b3af89 [SILDiagnostics] Move static enforcement enablement early return earlier. 
This avoids computing the PostOrderAnalysis when this pass won't use it
because static checks are disabled.

095083e0e8 CopyForwarding: new optimization to remove copies into dead temporaries. 
A SILGen peephole currently handles the common cases. However, that peephole
is incompatible with memory access enforcement.

2c87f08e3f [sil-generic-specializer] Don’t build a new generic signature in case of a full specialization. NFC. 
In case of a full specialization, the specialized function does not have a generic signature. Therefore there is no need to build it.
This speeds up the compilation by avoiding doing a useless work.

9dde2d7527 [SIL generics utils] Drastically simplify remapRequirements(). 
remapRequirements() was doing a whole lot of substitution work by
itself that the GenericSignatureBuilder is already capable of
doing. Use the GSB's functionality instead.

db58e02cb2 Sema: Hook up layout constraints to the solver 
There were various problems with layout constraints either
being ignored or handled incorrectly. Now that I've exercised
this support with an upcoming patch, there are some fixes
here.

Also, introduce a new ExistentialLayout::getLayoutConstriant()
which returns a value for existentials which are class-constrained
but don't have a superclass or any class-constrained protocols;
an example would be AnyObject, or AnyObject & P for some
non-class protocol P.

NFC for now, since these layout-constrained existentials cannot
be constructed yet.

6adcc2969e [semantic-sil] Change DefiniteInitialization to use the DIMemoryUseCollectorOwnership header instead of the normal DIMemoryUseCollector.

7d271cb444 [SILDiagnostics] Fix an invalidation crash in DiagnoseStaticExclusivity. 
Fix a crash when re-hashing the basic-block map would leave behind a dangling
mutable reference.

The irony that the language feature this pass implements would have caught this
issue statically is not lost on me.

b308daf311 [SILOpt] fix the ASAN issue in the new pass completely. 
LLVM's ilist::erase is actually correct. It just implements a nonstandard remove
method that modifies it's iterator argument.

I forgot to add "continue" statements when fixing the iterator-invalidation problem.

10ebdcd50a [GSB] Broaden the Boolean result of "add a constraint" operations. 
Rather than true (an error occurred) or false (the constraint was
resolved), introduce ConstraintResult to better model what
happened. NFC for now, but the intent here is to report unresolved
constraints through this mechanism.
