DSHIFTL — Combined left shiftDSHIFTL(I, J, SHIFT) combines bits of I and J. The
rightmost SHIFT bits of the result are the leftmost SHIFT
bits of J, and the remaining bits are the rightmost bits of
I.
RESULT = DSHIFTL(I, J, SHIFT)
| I | Shall be of type INTEGER.

| J | Shall be of type INTEGER, and of the same kind
as I.
