7fcad02dc2 fix RVV 1.0 detection code 
There were a couple of issues with the detection code used to check
for RVV 1.0 on kernels that do not support hwprobe.

1. The vtype clobber was missing
2. The wrong form of vsetvli was being used. The vsetvli x0, x0 form
   is inappropriate for this use case as it can only be safely used
   in code where the value of vtype is known.  The use of vsetvli
   x0, x0 here can lead to a failure to detect RVV 1.0, if,
   for example, the vill bit happens to be set before
   detect_riscv64_rvv100 is called.

We fix both issues by adding the missing clobber and replacing the
first parameter to vsetvli with t0 (which we add to our clobbers).

803e8d4838 Move the value assignment of vector x in gemv_n_sve.c to the outermost loop to reduce the repeated data retrieval. 
1.Verify correctness using BLAS-Tester
    2.Using the built-in benchmark to verify performance, the performance of float and doule type improved by about 60% and about 40% respectively.The test command is:
     export OMP_NUM_THREADS=1;numactl -C 10 -l ./sgemv.goto 3000 4000 100
     export OMP_NUM_THREADS=1;numactl -C 10 -l ./dgemv.goto 3000 4000 100

overall complexity of the inner GEMM loop.
