[PATCH] Fix v*i1 store size

[Hal Finkel]

Hello,

Please review the attached patch which fixes the storage size (in bytes) reported by DataLayout and MVT/EVT for v*i1 vectors. The current (incorrect) behavior is to round the total size in bits up and divide by 8. Instead, each element is stored in a separate byte, and so the result should be equal to the number of elements in the vector.

Thanks again,
Hal
