target/arm: Use FZ not FZ16 for SVE FCVT single-half and double-half 
We were using the wrong flush-to-zero bit for the non-half input.

Fixes: 46d33d1e3c9

target/arm: Fix offset scaling for LD_zprr and ST_zprr 
The scaling should be solely on the memory operation size; the number
of registers being loaded does not come in to the initial computation.

target/arm: Fix offset for LD1R instructions 
The immediate should be scaled by the size of the memory reference,
not the size of the elements into which it is loaded.

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.

target/arm: Fix do_predset for large VL 
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.

target/arm: Suppress Coverity warning for PRF 
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.

target/arm: Implement SVE fp complex multiply add (indexed) 
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.
