Reland [AArch64][DebugInfo] Do not recompute CalleeSavedStackSize (Take 2)
llvm/test/DebugInfo/MIR/X86/live-debug-values-reg-copy.mir failed with EXPENSIVE_CHECKS enabled, causing the patch to be reverted in rG2c496bb5309c972d59b11f05aee4782ddc087e71. This patch relands the patch with a proper fix to the live-debug-values-reg-copy.mir tests, by ensuring the MIR encodes the callee-saves correctly so that the CalleeSaved info is taken from MIR directly, rather than letting it be recalculated by the PEI pass. I've done this by running `llc -stop-before=prologepilog` on the LLVM IR as captured in the test files, adding the extra MOV instructions that were manually added in the original test file, then running `llc -run-pass=prologepilog` and finally re-added the comments for the MOV instructions.
