[SIL] Fix alloc_stack [dynamic_lifetime] attribute cloning.

Make SILCloner:visitAllocStack correctly propagate the [dynamic_lifetime] attribute.

Resolves SR-12886: differentiation transform error related to the VJPEmitter
subclass of SILCloner.

[AutoDiff] Fix SIL locations and debug scopes.

Fix SIL locations and debug scopes in VJPEmitter for:

  • Pullback struct struct instructions
  • Predecessor enums enum instructions

These instructions are not directly cloned from the original function and should
have auto-generated locations.

Resolves SR-12887: debug scope error for VJPEmitter-generated functions.

@gottesmm: would you like to sanity check this PR? It should not be controversial.

Typo: [dynamic_lifetime], not [dynamic_replacement].

The test for verification error SR-12886 added in the first commit revealed a second verification error SR-12887, so I pushed a fix for that too.

Updated PR title and description.

Linux and macOS platform tests have both flaked multiple times. I'll try smoke tests instead.
