[PowerPC]To provide better compatibility with gcc I added the __bool keyword to the Alitivec support in clang. __bool is functionally identical to using bool when declaring vector types. For example:

vector bool char v_bc;
vector __bool char v___bc;

clang already supported vector/__vector and pixel/__pixel but was missing __bool.
