I noticed that we don't set an itab's function pointers at compile time. Instead, we currently do it at executable startup. Set the function pointers at compile time instead. This shortens startup time. It has no effect on normal binary size. Object files will have more relocations, but that isn't a big deal. For PIE there are additional pointers that will need to be adjusted at load time. There are already other pointers in an itab that need to be adjusted, so the cache line will already be paged in. There might be some binary size overhead to mark these pointers. The "go test -c -buildmode=pie net/http" binary is 0.18% bigger.
