Richard Henderson 5698b7badb target/arm: Handle TBI for sve scalar + int memory ops
We still need to handle tbi for user-only when mte is inactive.

Richard Henderson 586235d02d target/arm: Add mte helpers for sve scalar + int ff/nf loads
Because the elements are sequential, we can eliminate many tests all
at once when the tag hits TCMA, or if the page(s) are not Tagged.

tcg: Specify optional vector requirements with a list
Replace the single opcode in .opc with a null-terminated
array in .opt_opc. We still require that all opcodes be
used with the same .vece.

Validate the contents of this list with CONFIG_DEBUG_TCG.
All tcg_gen_*_vec functions will check any list active
during .fniv expansion. Swap the active list in and out
as we expand other opcodes, or take control away from the
front-end function.

Convert all existing vector aware front ends.

decodetree: Remove insn argument from trans_* expanders
This allows trans_* expanders to be shared between decoders
for 32 and 16-bit insns, by not tying the expander to the
size of the insn that produced it.

This change requires adjusting the two existing users to match.

target/arm: Pass TCGMemOpIdx to sve memory helpers

or even put together the full TCGMemOpIdx. This can easily be
done at translation time.

target/arm: Clear unused predicate bits for LD1RQ
The 16-byte load only uses 16 predicate bits. But while
reusing the other load infrastructure, we find other bits
that are set and trigger an assert. To avoid this and
retain the assert, zero-extend the predicate that we pass
to the LD1 helper.

target/arm: Fix sign-extension in sve do_ldr/do_str
The expression (int) imm + (uint32_t) len_align turns into uint32_t
and thus with negative imm produces a memory operation at the wrong
offset. None of the numbers involved are particularly large, so
change everything to use int.

target/arm: Reorganize SVE WHILE
The pseudocode for this operation is an increment + compare loop,
so comparing <= the maximum integer produces an all-true predicate.

Rather than bound in both the inline code and the helper, pass the
helper the number of predicate bits to set instead of the number
of predicate elements to set.
