different number of elements.
Bitcasts were passing with vectors of pointers with different number of
elements since the number of elements was checking
SrcTy->getVectorNumElements() == SrcTy->getVectorNumElements() which
isn't helpful. The addrspacecast was also wrong, but that case at least
is caught by the verifier. Refactor bitcast and addrspacecast handling
in castIsValid to be more readable and fix this problem.

One form would accept a vector of pointers, and the other did not.
Make both accept vectors of pointers, and add an assertion
for the number of elements.

This avoids constant folding bitcast/ptrtoint/inttoptr combinations
that have illegal bitcasts between differently sized address spaces.

It will now only convert the arguments / return value and call
the underlying function if the types are able to be bitcasted.
This avoids using fp<->int conversions that would occur before.
