Update profile option documentation

Document all options that -fprofile-generate/-fprofile-usr select:

-fprofile-generate selects -fspeculative-prefetching
-fprofile-use selects -fprofile-values and -fspeculative-prefetching

I noticed -fprofile-generate does select -funroll-loops but I dont know why it
does (so didnt document it)
