mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes

Dan Gohman [Wed, 22 Apr 2009 16:11:16 +0000 (16:11 +0000)]
SCEVExpander's InsertCastOfTo knows how to move existing cast
instructions in order to avoid inserting new ones. However, if
the cast instruction is the SCEVExpander's InsertPt, this
causes subsequently emitted instructions to be inserted near
the cast, and not at the location of the original insert point.
Fix this by adjusting the insert point in such cases.
