Merged the separate patchsets I sent in the last couple of weeks into
one set. This will be easier to merge since it will avoid potential
merge conflicts due to adding max_insns to dc->base.

Changes since sending the separate series for sh4/sparc/mips/s390x/openrisc:
- Rebased on top of master (669743979)
- Added R-b's
- sh4: no changes since v3
- mips: no changes (no reviews yet!)
- sparc:
  + Use base.singlestep_enabled and singlestep like in other targets,
    e.g. Alpha.
  + Remove the unnecessary
     (dc.pc - pc_start) < (TARGET_PAGE_SIZE - 32))
- s390x:
  + Remove dc->pc, use pc_next instead as David suggested.
  + Use dc for DisasContext instead of s.
  + Compute next_page in translate_insn instead of keeping it in dc.
  + Looked into dropping dc->do_debug, but don't see an easy way to do so.
- openrisc:
  + Consistently use DISAS_NORETURN after generating an
    exception; fixed the two call sites that Richard pointed out,
    plus a couple of others that weren't visible in the previous patch.
  + Remove the dc->next_page_start field; instead, set the max_insn
    bound in translate_insn.

Curious to know what we would need to change in RISC-V translate.c:


I'm going to make a v8.1 branch and tag that is a rebase of the v8 patch series against current QEMU master, and hopefully we get the RISC-V port merged before the soft-freeze. Fingers crossed.
