mjit_compile.c: drop catch table handling
The loop for `vm_exce_handle_exception` doesn't trigger `mjit_exec`, so I don't think this code is no longer needed. This was needed in development of original version of this JIT, but it seems not needed from the beginning (r62189) at Ruby repository. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63520 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
