By now there are quite a few compilers that use feedback information to
improve code placement. I haven't seen any that use it for more
intelligent decisions, but presumably that'll become common during this
decade.

``Suggestions for compilation'' is too broad for me to answer the first
half of your question. Lots of languages and compilers let you make
suggestions for one thing or another.

What I'd love to see is a way to turn on optimizer debugging output for
a section of code. The optimizer would print out everything that it
looks for while optimizing, what it finds, and what it's not sure about.
Then the programmer can make assertions to fill in the missing gaps.
