[PULL 18/75] target/m68k: Remove unused @cpu_exception_index TCGv

Posted by Philippe Mathieu-Daudé 4 weeks, 1 day ago

When moving the @exception_index from each target ArchCPU
to the global CPUState in commit 27103424c40 ("cpu: Move
exception_index field from CPU_COMMON to CPUState"), the
@cpu_exception_index TCGv has been created for m68k target.

For years, no code ever used this register. Simply remove it.
