67c8c4caba Implement support for JIT exceptions on X86_64. Relative offsets are 
encoded on 32 bytes, and the personality function is not encoded as
relative.

2d093f3560 Avoid using a loop in ReleasePred and ReleaseSucc methods to compute the 
new CycleBound value. Instead, just update CycleBound on each call.
Also, make ReleasePred and ReleaseSucc methods more consistent accross
the various schedulers.

This also happens to make ScheduleDAGRRList's CycleBound computation
somewhat more interesting, though it still doesn't have any noticeable
effect, because no current targets that use the register-pressure
reduction scheduler provide pipeline models.

side-effects.
