Julian Seward fe4e6578d4 amd64 and x86 front ends: add a few more spec rules.
amd64:
  S and NS  after LOGICQ (per comments from Eyal Soha on the dev list)
  S         after SHLQ
  NZ        after SHLL

x86:
  NZ        after SHRL
  Z         after SHLL

I would have liked to have added the inverse conditions in all cases (eg, both
S and NS, or both Z and NZ), but finding use cases for some of these is almost
impossible, hence they are sometimes omitted.  All of the added cases have
been tested.
