This patch implements the LLVM intrinsics needed to implement the following prototypes of Vector Replace Builtins.

vector signed int vec_replace_elt (vector signed int, signed int, const int);
vector unsigned int vec_replace_elt (vector unsigned int, unsigned int, const int);
vector float vec_replace_elt (vector float, float, const int);
vector signed long long vec_replace_elt (vector signed long long, signed long long, const int);
vector unsigned long long vec_replace_elt (vector unsigned long long, unsigned long long, const int);
vector double rec_replace_elt (vector double, double, const int);

vector unsigned char vec_replace_unaligned (vector unsigned char, signed int, const int);
vector unsigned char vec_replace_unaligned (vector unsigned char, unsigned int, const int);
vector unsigned char vec_replace_unaligned (vector unsigned char, float, const int);
vector unsigned char vec_replace_unaligned (vector unsigned char, signed long long, const int);
vector unsigned char vec_replace_unaligned (vector unsigned char, unsigned long long, const int);
vector unsigned char vec_replace_unaligned (vector unsigned char, double, const int);
