As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.
The MIR printer prints the IR name of a MBB only for block definitions.

Add an option to allow easier experimentation by target maintainers with the
minimum number of entries to create jump tables. Also clarify the name of
the other existing option governing the creation of jump tables.

When there's a tie between partitionings of jump tables, consider also cases
that result in no jump tables, but in one or a few cases. The motivation is
that many contemporary processors typically perform case switches fairly
quickly.

Many high-performance processors have a dedicated branch predictor for
indirect branches, commonly used with jump tables. As sophisticated as such
branch predictors are, they tend to have well defined limits beyond which
their effectiveness is hampered or even nullified. One such limit is the
number of possible destinations for a given indirect branches that such
branch predictors can handle.
This patch considers a limit that a target may set to the number of
destination addresses in a jump table.
