In machine outliner implementation for AArch64, `signOutlinedFunction()`
reimplements signing the LR value in prologue and authenticating it in
epilogue of the outlined function. This patch factors out `signLR()` and
`authenticateLR()` functions from AArch64FrameLowering code and reuses
them in `signOutlinedFunction()`.
