Another caller-save buglet

[law@redhat.com]

This was found by inspection this morning.  It's bootstrapped 
i686-pc-linux-gnu;
I've also built mips-elf, mips64-elf and powerpc-eabi compilers and libraries
with this patch.

Installed into the mainline.

	* caller-save.c (init_caller_save): Move creation of SAVEINSN
	and RESTINSN into into the scope of the sequence.
