To simplify handling PAuth in the machine outliner, introduce a separate AArch64PointerAuth pass that is executed after both Prologue/Epilogue Inserter and Machine Outliner passes. After moving to AArch64PointerAuth, signLR and authenticateLR are not used outside of their class anymore, so make them private and simplify accordingly. The new pass is added via AArch64PassConfig::addPostBBSections(), so that it can change the code size before branch relaxation occurs. AArch64BranchTargets is placed there too, so it can take into account any PACI(A|B)SP instructions and not excessively add BTIs at the start of functions.

This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
