  [22.x][LoongArch] Revert musttail/byval/sret Changes

This reverts:
- 2b839f66ae0191039fb82049ec515bcbd726f612 (#168506)
- d40e607590770118f1d480fd02716fce505b3696 (#188006)

There's a lifetime issue in the implementation, where an SDValue is
saved and may be used outside the current basic block.

The corresponding revert on `main` is
501417baa60f2eb0a66ca3bb04caf70150ebc2f7 (#191508) - in this case only
the LoongArch changes made it to the 22.x branches, so this commit only
affects that architecture.
