comparison gen/optimizer.cpp @ 1507:f86fd3b77285

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Eliminate comparisons between GC allocations and constants. This removes some `assert(this !is null)`s when member functions get inlined. Also tweak pass order a bit.
