Subject: libgo patch committed: Default to -O2 when using the go tool

This libgo patch changes the go tool to default to invoking gccgo with
-O2.  That seems like the right default for people who choose to use
this toolchain.  It can be overridden with the go tool's -gccgoflags
option.  Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.
Committed to mainline.

Ian
