Go patch committed: build pointer type to types with methods

[Ian Lance Taylor]

The Go compiler always builds the pointer type for any named type, so
that it can attach methods in case the program calls reflect.PtrTo.
However, it didn't do that for unnamed types that happened to have
methods due to inheritance.  This patch fixes that problem.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.  Committed
to mainline.
