  Log Message:
  -----------
  [SveEmitter] Add builtins for ternary ops (fmla, fmad, etc)

This patch adds builtins for:
- svmad, svmla, svmls, svmsb
  svnmad, svnmla, svnmls, svnmsb
  svmla_lane, svmls_lane

These builtins come in several flavours:
- Merge into first source vector (`_m`)
- False lanes are undef (`_x`)
- False lanes are zeroed (`_z`)

And can also have `_n` to indicate the last operand is a scalar.

For example:

  svint32_t svmla[_n_s32]_z(svbool_t pg, svint32_t op1, svint32_t op2, int32_t op3)
