  Log Message:
  -----------
  [SVE] Generate overloaded functions for ACLE intrinsics.

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 *);

using the attribute:
  __clang_arm_builtin_alias

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