Add missing builtins to altivec.h for ABI compliance (vol. 3)

This patch corresponds to review:
http://reviews.llvm.org/D10972

Fix for the handling of dependent features that are enabled by default
on some CPU's (such as -mvsx, -mpower8-vector).

Also provides a number of new interfaces or fixes existing ones in
altivec.h.

Changed signatures to conform to ABI:
vector short vec_perm(vector signed short, vector signed short, vector unsigned char)
vector int vec_perm(vector signed int, vector signed int, vector unsigned char)
vector long long vec_perm(vector signed long long, vector signed long long, vector unsigned char)
vector signed char vec_sld(vector signed char, vector signed char, const int)
vector unsigned char vec_sld(vector unsigned char, vector unsigned char, const int)
vector bool char vec_sld(vector bool char, vector bool char, const int)
vector unsigned short vec_sld(vector unsigned short, vector unsigned short, const int)
vector signed short vec_sld(vector signed short, vector signed short, const int)
vector signed int vec_sld(vector signed int, vector signed int, const int)
vector unsigned int vec_sld(vector unsigned int, vector unsigned int, const int)
vector float vec_sld(vector float, vector float, const int)
vector signed char vec_splat(vector signed char, const int)
vector unsigned char vec_splat(vector unsigned char, const int)
vector bool char vec_splat(vector bool char, const int)
vector signed short vec_splat(vector signed short, const int)
vector unsigned short vec_splat(vector unsigned short, const int)
vector bool short vec_splat(vector bool short, const int)
vector pixel vec_splat(vector pixel, const int)
vector signed int vec_splat(vector signed int, const int)
vector unsigned int vec_splat(vector unsigned int, const int)
vector bool int vec_splat(vector bool int, const int)
vector float vec_splat(vector float, const int)

Added a VSX path to:
vector float vec_round(vector float)

Added interfaces:
vector signed char vec_eqv(vector signed char, vector signed char)
vector signed char vec_eqv(vector bool char, vector signed char)
vector signed char vec_eqv(vector signed char, vector bool char)
vector unsigned char vec_eqv(vector unsigned char, vector unsigned char)
vector unsigned char vec_eqv(vector bool char, vector unsigned char)
vector unsigned char vec_eqv(vector unsigned char, vector bool char)
vector signed short vec_eqv(vector signed short, vector signed short)
vector signed short vec_eqv(vector bool short, vector signed short)
vector signed short vec_eqv(vector signed short, vector bool short)
vector unsigned short vec_eqv(vector unsigned short, vector unsigned short)
vector unsigned short vec_eqv(vector bool short, vector unsigned short)
vector unsigned short vec_eqv(vector unsigned short, vector bool short)
vector signed int vec_eqv(vector signed int, vector signed int)
vector signed int vec_eqv(vector bool int, vector signed int)
vector signed int vec_eqv(vector signed int, vector bool int)
vector unsigned int vec_eqv(vector unsigned int, vector unsigned int)
vector unsigned int vec_eqv(vector bool int, vector unsigned int)
vector unsigned int vec_eqv(vector unsigned int, vector bool int)
vector signed long long vec_eqv(vector signed long long, vector signed long long)
vector signed long long vec_eqv(vector bool long long, vector signed long long)
vector signed long long vec_eqv(vector signed long long, vector bool long long)
vector unsigned long long vec_eqv(vector unsigned long long, vector unsigned long long)
vector unsigned long long vec_eqv(vector bool long long, vector unsigned long long)
vector unsigned long long vec_eqv(vector unsigned long long, vector bool long long)
vector float vec_eqv(vector float, vector float)
vector float vec_eqv(vector bool int, vector float)
vector float vec_eqv(vector float, vector bool int)
vector double vec_eqv(vector double, vector double)
vector double vec_eqv(vector bool long long, vector double)
vector double vec_eqv(vector double, vector bool long long)
vector bool long long vec_perm(vector bool long long, vector bool long long, vector unsigned char)
vector double vec_round(vector double)
vector double vec_splat(vector double, const int)
vector bool long long vec_splat(vector bool long long, const int)
vector signed long long vec_splat(vector signed long long, const int)
vector unsigned long long vec_splat(vector unsigned long long,
vector bool int vec_sld(vector bool int, vector bool int, const int)
vector bool short vec_sld(vector bool short, vector bool short, const int)
