Anton Korobeynikov 2f5492f572 Implement several peephole optimizations to unblock further optimizations of autodiff code (#60520 )

* Implement several peephole optimizations to unblock further optimizations of autodiff code

1. Simplify differentiable_function_extract of differentiable_function.
Before:
%x = differentiable_function(%orig, %jvp, %vjp)
%y = differentiable_function_extract [original] %x
After:
%y = %orig

2. Push conversion instructions inside of differentiable_function.
This unblocks inlining and specialization.
Before:
%x = differentiable_function(%orig, %jvp, %vjp)
%y = convert_escape_to_noescape %x
After:
%orig' = convert_escape_to_noescape %orig
%jvp' = convert_escape_to_noescape %jvp
%vjp' = convert_escape_to_noescape %vjp
%y = differentiable_function(%orig', %jvp', %vjp')

3. Another peephole is needed for reordering function conversion instructions to enable full inlining:
(convert_escape_to_noescape (convert_function (thin_to_thick_function x)))
=>
(convert_escape_to_noescape (thin_to_thick_function (convert_function x)))

* Remove broken disabled folding transform:
  - It is disabled
  - It is broken
  - It is certainly not something mandatory

ModuleInterface

ModuleInterface: Introduce the %target-swift-emit-module-interface and %target-swift-typecheck-module-from-interface lit substitutions and adopt them in some tests that involve emitting a swiftinterface. The substitutions specify the additional flags -swift-version 5 -enable-library-evolution. There are a few motivations for adding these substitutions:
