Sander de Smalen e877a2fb7c Relanding r368987 [AArch64] Change location of frame-record within callee-save area.
Changes:
There was a condition for `!NeedsFrameRecord` missing in the assert. The
assert in question has changed to:

+    assert((!RPI.isPaired() || !NeedsFrameRecord || RPI.Reg2 != AArch64::FP ||
+            RPI.Reg1 == AArch64::LR) &&
+           "FrameRecord must be allocated together with LR");

This addresses PR43016.
