Several problems fixed in this patch :
1) Target of the conditional jump in case a divide by 0 is performed
by a bpf is wrong.
2) Must 'generate' the full function prologue/epilogue at pass=0,
or else we can stop too early in pass=1 if the proglen doesnt change.
(if the increase of prologue/epilogue equals decrease of all
instructions length because some jumps are converted to near jumps)
3) Change the wrong length detection at the end of code generation to
issue a more explicit message, no need for a full stack trace.
