00a648ab - [X86] Elect to tail call when `sret` ptr is passed to the callee

[X86] Elect to tail call when `sret` ptr is passed to the callee We may be able to allow the callee to be tail-called when the caller expects a `sret` pointer argument, as long as this pointer is forwarded to the callee. Fixes: https://github.com/llvm/llvm-project/issues/146303.
