Log message:
Add retguard for octeon/mips64.
For this architecture we use separate retguard prologue and epilogue code
for static or PIC code. In the PIC case we use some additional code before
the retguard epilogue to recover the function start address and the GOT
pointer in order to get the per-function random cookie. Much thanks to
visa@ for suggestions and advice making it all work.
