SuccessChanges

Summary

  1. Fix cppcheck reduce scope variable warnings. NFCI Move a couple of variables inside the block where they are actually needed.
  2. Revert "Fix asan infinite loop on undefined symbol" This reverts commit cbd28cd05bb11e9d76d71c6cc2d38d89dbb1fe1a. Buildbot fail: http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/22434/steps/64-bit%20check-asan-dynamic/
  3. [Local] Zap blockaddress without users in ConstantFoldTerminator. If the blockaddress is not destoryed, the destination block will still be marked as having its address taken, limiting further transformations. I think there are other places where the dead blockaddress constants are kept around, I'll look into that as follow up.

  4. Fix asan infinite loop on undefined symbol Fix llvm#39641 Recommit of r366413 Differential Revision: https://reviews.llvm.org/D63877
  5. [c++20] P1161R3: a[b,c] is deprecated.
  6. Mark P1301R4 in C++2a as being SVN instead.
  7. We support P1301R4 in C++2a as of r366626.
  8. [cxx_status] Update status page for WG21 Cologne meeting motions. Note that many of the paper links will be dead until the post-meeting mailing is released.
  9. Implement P1301R4, which allows specifying an optional message on the [[nodiscard]] attribute. This also bumps the attribute feature test value and introduces the notion of a C++2a extension warning.

Revision 366633 by fhahn:
[Local] Zap blockaddress without users in ConstantFoldTerminator.

If the blockaddress is not destoryed, the destination block will still
be marked as having its address taken, limiting further transformations.

I think there are other places where the dead blockaddress constants are kept
around, I'll look into that as follow up.
