Nathan Huckleberry 6dc5fd93b2 ARM: 8900/1: UNWINDER_FRAME_POINTER implementation for Clang ...

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.
