BACKPORT: ARM: 8900/1: UNWINDER_FRAME_POINTER implementation for Clang

commit 6dc5fd93b2f1ef75d5e50fced8cb193811f25f22 upstream.

The stackframe setup when compiled with clang is different.
Since the stack unwinder expects the gcc stackframe setup it
fails to print backtraces. This patch adds support for the
clang stackframe setup.
