Fix #4914 (I hope) Here's a bit of erroneous code: 00000c5c <s1ad_info>: c5c: 8b 45 08 mov 0x8(%ebp),%eax c5f: d9 46 03 flds 0x3(%esi) c62: dd d9 fstp %st(1) c64: d9 55 08 fsts 0x8(%ebp) c67: 89 c6 mov %eax,%esi c69: c7 45 00 24 0c 00 00 movl $0xc24,0x0(%ebp) c70: f7 c6 03 00 00 00 test $0x3,%esi c76: 75 ac jne c24 <s1ac_info> So we should be doing some ffrees before the jne. The code that inserts the ffrees wasn't expecting to do it for a conditional jump, because they are usually local, but we have a late optimisation that shortcuts jumps-to-jumps, and that can result in a non-local conditional jump. This at least fixes an instance of the bug that I was able to reproduce, let's hope there aren't any more.
