bit-bash-copy can't handle very large objects

[rtoy]

BIT-BASH-COPY takes bit indices as offsets for copying random objects. This is very useful if we're copying bit-arrays or arrays with elements smaller than a byte. However, when copying strings or arrays with elements larger than a byte, the bit index exceeds 32 bits when the index is near MOST-POSITIVE-FIXNUM.

BIT-BASH-COPY needs to be updated to handle this, or a BYTE-BASH-COPY should be added to handle the case where the element size is at least a byte in size.
