[JVM] Fix shrinking of local range for dead variables.

Coroutine transform would occasionally *extend* the range of a
local instead of shrinking it (if the next suspension point
is after the end point for the local). That leads to the local
variable table having a local that covers code where it is not
defined. That is invalid and leads to D8 removing the locals
table from the code.
