header files relating to flow-sensitive analyses.  Moved
"DataflowValues.h" into this subdirectory.

checking being done in this patch.

"CheckDiagnostics" (used for -parse-ast-check) to check the
diagnostics of any ASTConsumer.

Reimplemented CheckDiagnostics to use CheckASTConsumer instead.

Added driver option -warn-dead-stores-check, which checks the
diagnostics generated by the DeadStores checker.  This is implemented
using CheckASTConsumer.111

nodes for DIV and IDIV which are introduced during the legalize phase
so that the SelectionDAG's CSE can automatically eliminate redundant
computations.
