The commit r369122 may keep LR and FP register (aka. frame record) in the middle of a frame, thus we must add the offsets to ensure the FP register always points to innermost frame record on the stack. According to AAPCS64[1], a conforming code shall construct a linked list of stack frames that can be traversed with frame records. This commit is also essential to frame-pointer-based stack unwinder (e.g. the stack unwinder in linx-perf-tools.)
