Ahmed Bougacha 199fa13fff [TableGen][DAGISel] Dedup predicates with same code to run. NFCI.
I locally hit the 255 limit, but a lot of these are redundant: each
predicate coming from a different record was allocated a new number,
even when we already emitted the same code for another predicate.

Instead, re-use numbers and emit the predicate code only once.
This reduces the total text size of *DAGISel.cpp.o by ~1%.
