Changes since v5:
* Fix the debug assertion ifdef in the final patch.
* Add more calls to arm_rebuild_hflags: CPSR and M-profile
These become two new patches, 18 & 19.
* Update some comments per review. (Alex)
Changes since v4:
* Split patch 1 into 15 smaller patches.
* Cache the new DEBUG_TARGET_EL field.
* Split out m-profile hflags separately from a-profile 32-bit.
* Move around non-cached tb flags as well, avoiding repetitive
checks for m-profile or other mutually exclusive conditions.
I haven't officially re-run the performance test quoted in the
last patch, but I have eyeballed "perf top", and have dug into
the compiled code a bit, which resulted in a few of the new
cleanup patches (e.g. cs_base, arm_mmu_idx_el, and
arm_cpu_data_is_big_endian).
Changes since v3:
* Rebase.
* Do not cache XSCALE_CPAR now that it overlaps VECSTRIDE.
* Leave the new v7m bits as uncached. I haven't figured
out all of the ways fpccr is modified.
Changes since v2:
* Do not cache VECLEN, VECSTRIDE, VFPEN.
These variables come from VFP_FPSCR and VFP_FPEXC, not from
system control registers.
* Move HANDLER and STACKCHECK to rebuild_hflags_a32,
instead of building them in rebuild_hflags_common.
Changes since v1:
* Apparently I had started a last-minute API change, and failed to
covert all of the users, and also failed to re-test afterward.
* Retain assertions for --enable-debug-tcg.
