Generalize target-independent folding rules for sizeof to handle more cases, and implement target-independent folding rules for alignof and offsetof. Also, reassociate reassociative operators when it leads to more folding. Generalize ScalarEvolution's isOffsetOf to recognize offsetof on arrays. Rename getAllocSizeExpr to getSizeOfExpr, and getFieldOffsetExpr to getOffsetOfExpr, for consistency with analagous ConstantExpr routines. Make the target-dependent folder promote GEP array indices to pointer-sized integers, to make implicit casting explicit and exposed to subsequent folding. And add a bunch of testcases for this new functionality, and a bunch of related existing functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94987 91177308-0d34-0410-b5e6-96231b3b80d8

Remove the folding rule getelementptr (i8* inttoptr (i64 1 to i8*), i32 -1) to inttoptr (i64 0 to i8*) from the VMCore constant folder. It didn't handle sign-extension properly in the case where the source integer is smaller than a pointer size. And, it relied on an assumption about sizeof(i8). The Analysis constant folder still folds these kinds of things; it has access to TargetData, so it can do them right. Add a testcase which tests that the VMCore constant folder doesn't miscompile this, and that the Analysis folder does fold it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94750 91177308-0d34-0410-b5e6-96231b3b80d8

Remove the folding rule getelementptr (i8* inttoptr (i64 1 to i8*), i32 -1) to inttoptr (i64 0 to i8*) from the VMCore constant folder. It didn't handle sign-extension properly in the case where the source integer is smaller than a pointer size. And, it relied on an assumption about sizeof(i8). The Analysis constant folder still folds these kinds of things; it has access to TargetData, so it can do them right.
