vmul -- vector multiplication
single-precision:
 Vector-Vector:
   -1 -- Vector<        float > * Vector<        float >
   -2 -- Vector<complex<float>> * Vector<complex<float>>
   -3 -- Vector<complex<float>> * Vector<complex<float>> (INTER)
   -4 -- Vector<complex<float>> * Vector<complex<float>> (SPLIT)
   -5 -- Vector<        float > * Vector<complex<float>>

  -21 -- t_vmul_dom1
  -22 -- t_vmul_dom1
  -31 -- t_vmul_ip1
  -32 -- t_vmul_ip1
 Vector-Vector (using explicit get()/put()):
  -41 -- Vector<        float > * Vector<        float >
  -42 -- Vector<complex<float>> * Vector<complex<float>>
 Vector-Vector (using mul() function):
  -51 -- mul(Vector<        float >, Vector<        float >)
  -52 -- mul(Vector<complex<float>>, Vector<complex<float>>)

double-precision:
  (101-113)
