Properly emit the pseudo instruction for conditional branch, so that we
can fix up conditional branches whose displacements are too large.
Reserve the right amount of opcode space for said pseudo instructions.

dont' regen the whole dag if unneccesary. Second, fix and ugly bug with

the only one to be trusted though.
