Reimplement r114460 in target-independent DAGCombine rather than target-dependent, by using the predicate to discover the number of sign bits. Enhance X86's target lowering to provide a useful response to this query. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114473 91177308-0d34-0410-b5e6-96231b3b80d8
