This patch implements support for the type vector bool int128
for arguments on vector comparison builtins listed below,
which would otherwise crash due to ambiguity.
The following builtins are added:
vec_all_eq (vector bool __int128, vector bool __int128) vec_all_ne (vector bool __int128, vector bool __int128) vec_any_eq (vector bool __int128, vector bool __int128) vec_any_ne (vector bool __int128, vector bool __int128) vec_cmpne(vector bool __int128 a, vector bool __int128 b) vec_cmpeq(vector bool __int128 a, vector bool __int128 b)
