  Log Message:
  -----------
  [Inliner] Fix bug where attributes are propagated incorrectly (#109347)

- **[Inliner] Add tests for incorrect propagation of return attrs; NFC**
- **[Inliner] Fix bug where attributes are propagated incorrectly**

The bug stems from the fact that we assume the new (inlined) callsite
is calling the same function as the original (callee) callsite. While
this is typically the case, since `VMap` simplifies the new
instructions, callee intrinsics callsites can end up not corresponding
with the same function.

This can lead to buggy propagation.
