We can choose the endianness at translation time, rather than
re-computing it at execution time.
Backports commit 7d0a57a2e1cea188b9023261a404d7a211117230 from qemu
This fixes the endianness problem for softmmu, and moves
the main loop out of a macro and into an inlined function.

Backports commit d4f75f25b43041e7a46d12352b3c70ae457d8cea from qemu
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.
Backports commit 2a99ab2b3545133961de034df27e24f4c22e3707 from qemu
We were using the wrong flush-to-zero bit for the non-half input.

Backports commit e4ab5124a5c2e2291006b24bdc21c3dd8d087ff4 from qemu
The scaling should be solely on the memory operation size; the number
of registers being loaded does not come in to the initial computation.
Backports commit 50ef1cbf31caad21019ae6fa8036ed6f29244ba5 from qemu
The immediate should be scaled by the size of the memory reference,
not the size of the elements into which it is loaded.
Backports commit d0e372b0298f897993f831dbff7ad4f1c70f138e from qemu
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.
Backports commit 19f2acc915a0f8f443a959844540a6f09133cc96 from qemu
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.
Backports commit bbd0968c458d48e34a08b8694fa3309a9fe1c9e7 from qemu
Use MAKE_64BIT_MASK instead of open-coding. Remove an odd
vector size check that is unlikely to be more profitable
than 3 64-bit integer stores. Correct the iteration for WORD
to avoid writing too much data.
Fixes RISU tests of PTRUE for VL 256.
Backports commit 973558a3f869e591d2406dd8226ec0c4e32a3c3e from qemu
These instructions must perform the sve_access_check, but
since they are implemented as NOPs there is no generated
code to elide when the access check fails.
Backports commit 2f95a3b09aebdcb5c9152a7ac434a5d57441fe82 from qemu
Enhance the existing helpers to support SVE, which takes the
index from each 128-bit segment. The change has no effect
for AdvSIMD, since there is only one such segment.
