Because Go uses explicit package imports, and because imports may not
have cycles, a lot of work that can only be done at link time for
C-like languages can be done at compile time by Go. For example, the
single biggest gain from LTO for C is inlining functions across
different object files. But the Go compiler does this at compile
time.

So let me turn the question around: what advantages would you expect
to see from using LTO in the Go linker?
