This patch implements the following function prototypes to utilize the `vmulh[s|u][w|d]` and `vdive[s|u][w|d]` instructions:

  vector signed int vec_mulh (vector signed int a, vector signed int b);  
  vector unsigned int vec_mulh (vector unsigned int a, vector unsigned int b); 
  vector signed long long vec_mulh (vector signed long long a, vector signed long long b); 
  vector unsigned long long vec_mulh (vector unsigned long long a, vector unsigned long long b);
  
  vector signed int vec_dive (vector signed int a, vector signed int b);
  vector unsigned int vec_dive (vector unsigned int a, vector unsigned int b);
  vector signed long long vec_dive (vector signed long long a, vector signed long long b);
  vector unsigned long long vec_dive (vector unsigned long long a, vector unsigned long long b);
