Merge patch from JeremyF:
72-jump
Add some codegen infrastructure to make it easier to generate local
jumps. If you want to generate a local backwards jump, use
VG_(init_target)(&tgt) to initialize the target descriptor, then
VG_(emit_target_back)(&tgt) just before emitting the target
instruction. Then, when emitting the delta for the jump, call
VG_(emit_delta)(&tgt).
Forward jumps are analogous, except that you call VG_(emit_delta)()
then VG_(emit_target_forward)().
The new emit function, VG_(emit_jcondshort_target)() takes a target
pointer rather than a delta.
