GCC 4.4.0 has been released. There are many interesting changes, including the merge of the Graphite branch, which is "a new framework for loop optimizations based on a polyhedral intermediate representation", improved support of the upcoming C++0x standard, and a new register allocator.

Haven't had a chance to try it yet, but the new graphite loop optimization framework should potentially give some speedups. Personally the '-fprofile-correction' option will help me since I've had some problems on certain programs with corrupted profiles. As for the llvm performance, can you point me to any benchmarks which shows gcc versus llvm?
