Update INSN_ADDRESSES for insns within a fixed length SEQUENCE.

[Graham Stott <grahams at redhat dot com>]

All

While fixing a branch shortening failure on the MIPS I found it
annoying that instructions that are part of a fix length insn
which is a SEQUENCE don't have their INSN_ADDRESSES.

This patch updates the INSN_ADDRESSES for such instructions.

Bootstrapped and tested x86, mips and arm.

	* final.c (shorten_branches): Update the INSN_ADDRESSES of
	insns within fixed length SEQUENCE.
