We were treating psw.mask as the 32-bit quantity it is in ESA mode.
In particular, the CC field was at the wrong place.

Yes, we're about to rewrite all of this, but having this unconditional
jump recompute cc_op is a large source of "false diff errors" when
trying to examine before and after dumps.

DISAS_EXCP is exit via exception; we wanted DISAS_JUMP.

At the same time, tidy other usages of tcg_gen_deposit_i64.
In some cases we can "type cast" rather than extend, and in
others we can allow tcg_gen_deposit_i64 itself to optimize
the HOST_LONG_BITS==32 case.

The blank lines inside the single dump make it difficult for the
eye to pick out the block.  Worse, with interior newlines, but
no blank line following, the PSW line appears to belong to the
next dump block.

tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by
type casts of pointer to tcg_target_long.

These changes are needed for build environments where
sizeof(long) != sizeof(void *), especially for w64.

See 4b4a72e5 which fixed the
same issue for the other targets.

The disas_a5() function provided a TCG tmp variable which was populated
by the respective opcode implementations, but freed at the end of the
function in generic code.

That makes it really hard for code review, so let's move the freeing
to the same scope as the actual allocation.
