  Log Message:
  -----------
  [SveEmitter] Add builtins to insert/extract subvectors from tuples (svget/svset)

For example:
  svint32_t svget4(svint32x4_t tuple, uint64_t imm_index)

returns the subvector at `index`, which must be in range `0..3`.
  svint32x3_t svset3(svint32x3_t tuple, uint64_t index, svint32_t vec)

returns a tuple vector with `vec` inserted into `tuple` at `index`,
which must be in range `0..2`.
