Revert "AArch64: Fix frame record chain"

Breaks aosp-O3-polly-before-vectorizer-unprofitable with the following
error message:

void llvm::emitFrameOffset(llvm::MachineBasicBlock &,
MachineBasicBlock::iterator, const llvm::DebugLoc &, unsigned int,
unsigned int, llvm::StackOffset, const llvm::TargetInstrInfo *,
MachineInstr::MIFlag, bool, bool, bool *): Assertion `(DestReg !=
AArch64::SP || Bytes % 16 == 0) && "SP increment/decrement not 16-byte
aligned"' failed.

This reverts commit d4e10e6a.
