This will collect all load and store helpers soon.  For now
it is just a replacement for softmmu_exec.h, which this patch
stops including directly, but we also include it where this will
be necessary in order to simplify the next patch.

Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h.  This
minimizes the files that must be rebuilt when changing the macros
for file N.

Don't load the displacement into a register first, add it second
so that tcg_gen_addi_i64 can eliminate zeros.  Don't mask the
displacement first so that we don't turn small negative numbers
into large positive numbers.

Giving the proper mask to disas_jcc allows us to generate an inline
comparison generating the carry/borrow with setcond.

In the very worst case, when we must use the external helper to compute
a value for CC, we generate (cc > 1) instead of (cc >> 1), which is only
very slightly slower on common cpus.

In the very best case, when the CC comes from a COMPARE insn and the
compiler is using ALCG with zero, everything folds out to become just
the setcond that the compiler wanted.

After full conversion, we can audit the uses of LTGT cc ops
and see that none of the instructions can ever set CC=3.
Thus we can extend the table to treat that bit as ignored.

This fixes a regression wrt the pre-conversion translation
in which NE was used for both m=6 and m=7.

There's no need to force computation of the true cc_op when taking an
exception or single stepping.  In either case we'll enter the next TB
with s->cc_op = DYNAMIC and recompute anyway.  Just make sure that
s->cc_op is stored back to env->cc_op as needed.

Delete some dead functions, avoid allocating unused TCG temps, drop
the old s->is_jmp setting.
