Pavel Yaskevich 60ea598e7f [SIL] Set actor isolation when constructing/initializing SILFunction
Prevents situations when actor isolation ends up not being set
un-intentionally i.e. when cloning, specializating, or creating
thunks.

The thunks get `unspecified` isolation at the moment.

Pavel Yaskevich 883d4ce45b [SIL] Drop optional from SILFunction::getActorIsolation
SIL functions should always have actor isolation set, otherwise
it could lead to wrong deductions in optimization passes like
`SendNonSendable` or `OptimizeHopToExecutor`.

This is a first step to move isolation assignment into
`SILFunction::create`.

Pavel Yaskevich f01d91f079 [SILOptimizer] Make sure that cloning also transfers the actor isolation
There are passes that rely on the isolation being present after
specialization and other optmizations i.e. `SendNonSendable` which
means the clones need to always preserve the isolation of the
original function.

Daniil Kovalev 1f77138afe [AutoDiff] Closure specialization: specialize branch tracing enums (#85757)
This patch contains part of the changes intended to resolve #68944.

1. Closure info gathering logic.
2. Branch tracing enum specialization logic.
3. Specialization of branch tracing enum basic block arguments in VJP.
4. Specialization of branch tracing enum payload basic block arguments
in pullback.

Note that mangling-related logic is implemented in C++ since at this
moment we have no Swift bridged for that.

Here is a simplified example of how branch tracing enum (BTE)
specialization looks like.

Before specialization:

```
enum $_AD__xxx {
  case bb0(((Float) -> Float))
}

func vjp(...) {
  // ...
  %foo      = function_ref $foo         : (Float, Float) -> Float
  %pa1      = partial_apply %foo(%arg1) : (Float) -> Float
  %payload1 = tuple (%pa1)              : ((Float) -> Float)
  %bte      = enum $_AD__xxx.bb0!enumelt, %payload1
  // ...
}

func pullback(%bte, ...) {
  // ...
  %payload2 = unchecked_enum_data %bte, $_AD__xxx.bb0!enumelt : ((Float) -> Float)
  %pa2      = tuple_extract %payload2, 0                      : (Float) -> Float
  %res      = apply %pa2(%arg2)                               : Float
  // ...
}
```

After specialization:

```
enum $_AD__xxx_spec_bb0_0 {
  case bb0(((Float)))
}

func vjp(...) {
  // ...
  %captured1 = tuple (%arg1)      : (Float)
  %payload1  = tuple (%captured1) : ((Float))
  %bte_spec  = enum $_AD__xxx_spec_bb0_0.bb0!enumelt, %payload1
  // ...
}

func pullback_spec(%bte_spec, ...) {
  // ...
  %payload2  = unchecked_enum_data %bte, $_AD__xxx_spec_bb0_0.bb0!enumelt : ((Float))
  %captured2 = tuple_extract %payload2, 0                                 : (Float)
  %arg1      = tuple_extract %captured2, 0                                : Float
  %foo       = function_ref $foo                                          : (Float, Float) -> Float
  %res       = apply %foo(%arg2, %arg1)                                   : Float
  // ...
}
```

Erik Eckstein 89bba668e2 Mangling: add a closure specialization mangling for arguments which specialize for the same closure as a previous argument
For example:
```
  %1 = partial_apply %closure
  apply %f(%1, %1)    // first argument: `.closure(%1)`
                      // second argument: `.previousArgumentIndex(0)`
```

Erik Eckstein 1a4bd76f95 Mangling: add specialization mangling for more complex constant propagated function arguments
So far, constant propagated arguments could only be builtin literals.
Now we support arbitrary structs (with constant arguments), e.g. `Int`.
This requires a small addition in the mangling scheme for function specializations.
Also, the de-mangling tree now looks a bit different to support a "tree" of structs and literals.

Erik Eckstein 65c9828cb3 SwiftCompilerSources: move the Context protocols from the Optimizer to the SIL module
This allows to move many SIL APIs and utilities, which require a context, to the SIL module.

The SIL-part of SwiftPassInvocation is extracted into a base class SILContext which now lives in SIL.

Also: simplify the begin/end-pass functions of the SwiftPassInvocation.
