Mark GT_IND nodes that represent VSD targets.
The operand to such a node must be materialized into a register on
certain platforms. This change defines a new IND-specific flag,
GTF_IND_VSD_TGT, and uses that flag to indicate that a particular
GT_IND node represents a VSD target. This flag is then observed by
lowering on the necessary platforms in order to short circuit the
logic that attempts to make the GT_IND's operand contained.
