Most changes are in comments, one modifies a parameter name in a function
prototype.
The spelling fixes were made using codespell.

The gen_icount_start/end functions are now somewhat misnamed since they
are useful for generic "start/end of TB" code, used for more than just
icount. Rename them to gen_tb_start/end.

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.

While they aren't expensive, they aren't free to process. When we
know that the three cc helper variables are dead, don't kill them.

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.

The use of inline restricts detection of static functions that are
no longer used. Limit the use of inline to those functions that
are conditionally used based on CONFIG_USER_ONLY.

While we're at it, list all of the chapter 14 subchannel insns.
Which is easy since all merely need indicate non-operation.
