RFC: Jump to const_int

One further thought.  The test looks bogus to me because the address
clearly can't be in the current function.  Thus, the behavior of such
a jump is totally unpredictable.

Gcc allows as an extension goto's to any void * expression.  Thus, the
above is accepted but it will clearly cause problems when edges are
to be calculated.
