Preserve value numbers when morphing multiplication into shift.

This change fixes a morpher transformation of multiplication to shift
to preserve the value number of the tree since the new shift expression
will compute the same value as the old multiplication expression.
Without that change we were getting  asserts in fgMoveOpsLeft,
which expects to see value numbers on trees it transforms.

Closes #2920.
