instead use cpu_cc_dst like the others.

target/i386: decode address before going back to translate.c
There are now relatively few unconverted opcodes in translate.c (there
are 13 of them including 8 for x87), and all of them have the same
format with a mod/rm byte and no immediate. A good next step is
to remove the early bail out to disas_insn_x87/disas_insn_old,
instead giving these legacy translator functions the same prototype
as the other gen_* functions.
To do this, the X86DecodeInsn can be passed down to the places that
used to fetch address bytes from the instruction stream. To make
sure that everything is done cleanly, the CPUX86State* argument is
removed.
As part of the unification, the gen_lea_modrm() name is now free,
so rename gen_load_ea() to gen_lea_modrm(). This is as good a name
and it makes the changes to translate.c easier to review.

This moves the last LOCK-enabled instructions to the new decoder. It is now
possible to assume that PREFIX_LOCK gen_multi0F is called only after checking
that LOCK was not specified.
The gen_cmpxchg8b and gen_cmpxchg16b functions even have the correct
prototype already; the only thing that needs to be done is removing the
gen_lea_modrm() call.

target/i386: remove gen_ext_tl
With the introduction of tcg_gen_ext_tl, most uses can be converted directly
because they do not have a NULL destination. tcg_gen_ext_tl is able to drop
no-ops like "tcg_gen_ext_tl(tcgv, tcgv, MO_TL)" just fine, and the only thing
that gen_ext_tl was adding on top was avoiding the creation of a useless
temporary. This can be done in the only place where it matters, which is
gen_op_j_ecx.

meson: allow configuring the x86-64 baseline
Add a Meson option to configure which x86-64 instruction
set to use. QEMU will now default to x86-64-v1 + cmpxchg16b for
64-bit builds (that corresponds to a Pentium 4 for 32-bit builds).
The baseline can be tuned down to Pentium Pro for 32-bit builds (with
-Dx86_version=0), or up as desired.
