[TLI] Pass replace-with-veclib works with Scalable Vectors. (#73642)

[TLI] Pass replace-with-veclib works with Scalable Vectors.

The pass is heavily refactored.
It uses the Masked variant of a TLI method when the Intrinsic operates on Scalable Vectors.

 Improve tests for ArmPL and SLEEF Intrinsics:
- Auto-generate test `armpl-intrinsics.ll`, and use active lane mask to have shorter `shufflevector` check lines.
- Update scripts now add `@llvm.compiler.used` instead of using the regex: `@[[LLVM_COMPILER_USED:[a-zA-Z0-9_$"\\.-]+]]`
-  Add simplifycfg pass and noalias to ensure tail folding. `noalias` attribute was added only to the `%in.ptr` parameter of the ArmPL Intrinsics.
