<pre>
    As code is:
https://godbolt.org/z/KM5z873Yz

This case is from the gnu deja test  gcc.target/aarch64/advsimd-intrinsics/vqsub.c

I simplify the case for only test one small case.    The case call the neon vqsubq_s64() intrinsics and test the fpsr.QC bit

Set FPSR，  then sqsbu, then got FPSR.QC
>From the asm, it seems that "sqsub" is move up "msr fpsr" inst.
