The SVE ACLE allows using a short-form for the intrinsics, e.g.
the following two declarations generate the same code:

    
  svuint32_t svld1(svbool_t, uint32_t const *);
  svuint32_t svld1_u32(svbool_t, uint32_t const *);
    

This patch also adds the attribute:

  __clang_arm_sve_alias
    

similar to what has been done for MVE in:

  https://reviews.llvm.org/D67159
    

so that any call to svld1(svbool_t, uint32_t const *) will
map to __builtin_sve_svld1_u32.
