[llvm] Remove pipeline checks for optsize for DFAJumpThreadingPass

The pass itself checks whether to apply the optimization based on the
minsize attribute, so there isn't much functional benefit to preventing
the pass from being added. Gating the pass gets added to the pass
pipeline complicates the interaction with -enable-dfa-jump-thread, as
well.
