           Summary: ICE when goto into try/catch block

The test case:

void main()
{
   goto L1;
   try { L1: { } }
   catch { }
}

Results in an ICE when trying to compile.

Internal error: ../ztc/cgcod.c 989


Similarly, this produces bad codegen.

void main()
{
   goto L1;
   try { }
   catch { L1: { } }
}

And a segmentation fault occurs during runtime. My guess is that because the
try{} body is empty, the entire block gets optimised out, but the goto
statement is still left in, where it now jumps to an invalid/null address.
