while this is resonable thing to do, I belive it would make most sense
to make switch lowering at gimple level: i.e. reorganize the existing
code to produce gimple statement and change expansion code to produce
tablejump from every gimple switch statement that was left in the

This would be both cleaner and would allow gimple optimizers to improve the
generated code. Incrementally it would also allow us to improve switch exansion
that is quite baroque and not realy producing very good code in some common

If you would be interested working on this (i.e. reorganizing the expansion
code to produce gimple), I would be very happy. If not, I can review the
profile updating part for mainline, since in any case this is desriable thing
to do.
