Andrea Di Biagio d47cb57ab8 [DAG] Fix an assertion failure caused by an invalid cast in method 'BuildVectorSDNode::isConstantSplat' 
This patch renames method 'isConstantSplat' as 'getConstantSplatValue'
(mainly for consistency reasons), and rewrites its logic to ensure
that we always perform a legal 'cast<ConstantSDNode>'.

Added test shift-combine-crash.ll to verify that DAGCombiner no longer crashes with an assertion failure in the attempt to simplify a vector shift by a vector of all undef counts.

ADT When destroying a StringMap, just iterate over the map and destroy the contained elements. Don't reset them back to 0 as their values aren't needed any more. This results in ~StringMap() being mostly empty for POD types in BumpPtrAllocators 2014-03-19 00:23:30 +00:00
