  [PowerPC] Implement Elliptic Curve Cryptography Builtins (#184681)

Add support for the following ISA Future elliptic curve cryptograpy
builtins.

* Builtins with immediate parameters:
vector unsigned char __builtin_xxmulmul(vector unsigned char, vector
unsigned char, unsigned int);
vector unsigned char __builtin_xxmulmulhiadd(vector unsigned char,
vector unsigned char, unsigned int, unsigned int, unsigned int); vector
unsigned char __builtin_xxmulmulloadd(vector unsigned char, vector
unsigned char, unsigned int, unsigned int); vector unsigned char
__builtin_xxssumudm(vector unsigned char, vector unsigned char, unsigned
int);
vector unsigned char __builtin_xxssumudmc(vector unsigned char, vector
unsigned char, unsigned int);
vector unsigned char __builtin_xxssumudmcext(vector unsigned char,
vector unsigned char, vector unsigned char, unsigned int);

* Builtins with two vector parameters (no immediates):
vector unsigned char __builtin_xsaddadduqm(vector unsigned char, vector
unsigned char);
vector unsigned char __builtin_xsaddaddsuqm(vector unsigned char, vector
unsigned char);
vector unsigned char __builtin_xsaddsubuqm(vector unsigned char, vector
unsigned char);
vector unsigned char __builtin_xsaddsubsuqm(vector unsigned char, vector
unsigned char);
vector unsigned char __builtin_xsmerge2t1uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsmerge2t2uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsmerge2t3uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsmerge3t1uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsrebase2t1uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsrebase2t2uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsrebase2t3uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsrebase2t4uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsrebase3t1uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsrebase3t2uqm(vector unsigned char,
vector unsigned char);
vector unsigned char __builtin_xsrebase3t3uqm(vector unsigned char,
vector unsigned char);
