-fwhopr and -flto options reorg

- Subject: -fwhopr and -flto options reorg
Hi,
this patch does the change discussed on gcc summit converting -fwhopr to -flto.
-flto=n and -flto=jobserv syntax is supported.
-flto can be done by -flto-partition=none -flto.
I did not made other changes, like enabling linker plugin by default or autodetecting
jobserv as this is boring and large enough already.
Bootstrapped/regtested x86_64-linux, OK?
