Re: PATCH: Relax AltiVec integral parameter/literal type checking

Continuing on my path to redemption...

This builds on Janis' discovery that AltiVec is now too strict (in the C
case, anyway) about requiring integral type parameters to have exactly
type 'int', which the AltiVec standard does not require; similar for
literal arguments. The solution is to _remove_ the type checks for
these integral parameters/literals, esp. since they don't add any
value in the overload resolution we're implementing.

So now no type checking will be done on these arguments? What if 2nd argument is not an integral type?

As you can see, this simplifies the C portion of altivec.h quite bit; for intrinsics that accept only integral parameters, the ..._args_eq tests have been removed completely.
