Reapply D70800: Fix AArch64 AAPCS frame record chain
Original Commit Message:
After the commit r368987 (rG643adb55769e) was landed, the frame record (FP and LR register)
may be placed in the middle of a stack frame if a function has both callee-saved
general-purpose registers and floating point registers. This will break the stack unwinders
that simply walk through the frame records (based on the guarantee from AAPCS64
"The Frame Pointer" section). This commit fixes the problem by adding the frame record offset.
