Davide Italiano 7dd0694f96 [GlobalOpt] Remove unreachable blocks before optimizing a function. ... LLVM's definition of dominance allows instructions that are cyclic in unreachable blocks, e.g.: %pat = select i1 %condition, @global, i16* %pat because any instruction dominates an instruction in a block that's not reachable from entry. So, remove unreachable blocks from the function, because a) there's no point in analyzing them and b) GlobalOpt should otherwise grow some more complicated logic to break these cycles.
