If both a compare operation and a branch exists, these are used in preference
to a cbranch handler.  If a compare operation, but no branch exists, the
cbranch handler is not used.  If no compare operation exists, we can't generate
compare / setcc sequences.  cstore patterns are recognized by genopinit, but
cause a compiler crash their presence influences code generation.
