Subject: [power7-meissner] Add copysign support to Altivec; Flesh out vec_* support for vector double

As per Paolo's suggestion, I added copysign support to the Altivec.

I went through altivec.h and added VSX vector double support to the generic
functions where it is appropriate (i.e. vec_add, vec_sub, etc.).  I added
several new vec_<xxx> function if VSX is a target (multiply, divide, sqrt,
etc.).

I fixed up the support for vector bool long, which is needed for the comparison
functions.
