Subject: [PATCH] refactor extract binop dispatcher

Those opt_something instructions are worth refactoring. They tend to
have similar ways of executions.  By extracting the common part,
generated vm_exec_core function shrinks from 26,816 bytes to 26,256
bytes (according to nm(1)).

Subject: [PATCH] re-introduce __builtin_add_overflow

r57789 (74cdd89) was gradually "improve"d by naruse through r57793 to
r57806, resulted in reverting the efect of r57789 while retaining its
complexity.  I think the current situation is slightly worse than
before (same output complicated source code).
