I don't think that JIT becomes easier by this change. Constructing the
IR for LLVM, libFirm or any other JIT library from expression trees is
straightforward already. It's probably more of a nuisance for those
that already have some code/design on JIT-compiling expressions
(vitessedb, ISP RAS, yours truly)
I like your patch for all the other reasons stated though!
