[CGExprScalar] In EmitCompare trunc the result if it has different type as E->getType()
Usually compare expression should return i1 type, so EmitScalarConversion is called before return
return EmitScalarConversion(Result, CGF.getContext().BoolTy, E->getType(), E->getExprLoc());
But when ppc intrinsic is called to compare vectors, the ppc intrinsic can return i32 even E->getType() is BoolTy, in this case EmitScalarConversion does nothing, an i32 type result is returned and causes crash later.
This patch detects this case and truncates the result before return.
