target/arm: Split contiguous stores for endianness 
We can choose the endianness at translation time, rather than
re-computing it at execution time.

Backports commit 28d57f2dc59c287e1c40239509b0a325fd00e32f from qemu

target/arm: Rewrite vector gather stores 
This fixes the endianness problem for softmmu, and moves
the main loop out of a macro and into an inlined function.

This fixes the endianness problem for softmmu, and moves the
main loop out of a macro and into an inlined function

target/arm: Rewrite helper_sve_ld[234]*_r 
Use the same *_tlb primitives as we use for ld1.

For linux-user, this hoists the set of helper_retaddr. For softmmu,
hoists the computation of the current mmu_idx outside the loop,
fixes the endianness problem, and moves the main loop out of a
macro and into an inlined function.

target/arm: Rewrite helper_sve_ld1*_r using pages 
Uses tlb_vaddr_to_host for correct operation with softmmu.
Optimize for accesses within a single page or pair of pages.

target/arm: Use fp_status_fp16 for do_fmpa_zpzzz_h 
This makes float16_muladd correctly use FZ16 not FZ.

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.

target/arm: Fix LD1W and LDFF1W (scalar plus vector) 
'I' was being double-incremented; correctly within the inner loop
and incorrectly within the outer loop.

target/arm: Fix SVE signed division vs x86 overflow exception 
We already check for the same condition within the normal integer
sdiv and sdiv64 helpers. Use a slightly different formation that
does not require deducing the expression type.
