7939e039e7 [RVV] Fix compile warning in row_rvv 
1. Fix compile warning in row_rvv.cc

2. Avoid compile row_rvv.cc/scale_rvv.cc when using GCC
There is no RVV segment load & store on GCC.
Hence, avoid compiling rvv code on GCC temporarily.

3. Add several compile options to cmake build flow
  -Wno-sign-compare
  -Wno-unused-function
  -Wunused-variable
  -Wuninitialized
