In commit d56fea79f9 ("tcg: Move TCG_{LOW,HIGH} to tcg-internal.h")
we replaced the "_link_error" definitions with modern QEMU_ERROR()
attribute markup. We covered tcg-op.c but forgot to completely
clean tcg-op-vec.c. Do it now.

From this remove, it's no longer clear what this is attempting

In preparation for compiling tcg/ only once, eliminate
the all_helpers array. Instantiate the info structs for
the generic helpers in accel/tcg/, and the structs for
the target-specific helpers in each translate.c.
Since we don't see all of the info structs at startup,
initialize at first use, using g_once_init_* to make
sure we don't race while doing so.

The symbol is always defined, even if to 0. We wanted to test for
TCG_OVERSIZED_GUEST == 0.
This fixed, the #error is reached while building arm-softmmu, because
TCG_OVERSIZED_GUEST is not true (nor supposed to be true) for arm32
guest on a 32-bit host. But that's ok, because this feature doesn't
apply to arm32. Add an #ifdef for TARGET_AARCH64.

This makes CPUTLBEntry agnostic to the address size of the guest.
When 32-bit addresses are in effect, we can simply read the low
32 bits of the 64-bit field. Similarly when we need to update
the field for setting TLB_NOTDIRTY.
For TCG backends that could in theory be big-endian, but in
practice are not (arm, loongarch, riscv), use QEMU_BUILD_BUG_ON
to document and ensure this is not accidentally missed.
For s390x, which is always big-endian, use HOST_BIG_ENDIAN anyway,
to document the reason for the adjustment.
For sparc64 and ppc64, always perform a 64-bit load, and rely on
the following 32-bit comparison to ignore the high bits.
Rearrange mips and ppc if ladders for clarity.
