When building with CONFIG_Q35=n, we get:
LINK x86_64-softmmu/qemu-system-x86_64
/usr/bin/ld: hw/i386/acpi-build.o: in function `acpi_get_misc_info':
/source/qemu/hw/i386/acpi-build.c:243: undefined reference to `ich9_lpc_find'
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:204: qemu-system-x86_64] Error 1
This is due to a dependency in acpi-build.c on the ICH9_LPC
(via ich9_lpc_find) and PIIX4_PM (via piix4_pm_find) devices.
To allow better modularity (compile acpi-build.c with only
Q35/ICH9 or ISAPC/PIIX4), refactor the similar helper as
object_resolve_type_unambiguous(). This way we relax the
linker dependencies and can build the x86 targets with a
selection of machines (instead of all of them).

The old -realtime mlock=on|off parameter does exactly the same as the

Allow the backend to expand dup from memory directly, instead of
forcing the value into a temp first. This is especially important
if integer/vector register moves do not exist.
Note that officially tcg_out_dupm_vec is allowed to fail.
If it did, we could fix this up relatively easily:
VECE == 32/64:
Load the value into a vector register, then dup.
Both of these must work.
VECE == 8/16:
If the value happens to be at an offset such that an aligned
load would place the desired value in the least significant
end of the register, go ahead and load w/garbage in high bits.
Load the value w/INDEX_op_ld{8,16}_i32.
Attempt a move directly to vector reg, which may fail.
Store the value into the backing store for OTS.
Load the value into the vector reg w/TCG_TYPE_I32, which must work.
Duplicate from the vector reg into itself, which must work.
All of which is well and good, except that all supported
hosts can support dupm for all vece, so all of the failure
paths would be dead code and untestable.

The i386 backend already has these functions, and the aarch64 backend
could easily split out one. Nothing is done with these functions yet,
but this will aid register allocation of INDEX_op_dup_vec in a later patch.
