[AssumeBundles] ValueTracking cannot use alignment assumptions?
Hello,
As I can see, recently LLVM switched to using assume bundles to encode alignment information: https://reviews.llvm.org/rG78de7297abe2e8fa782682168989c70e3cb34a5c
However, it seems that the ValueTracking cannot understand the new format. As an example, consider compilation of the following reproducer with clang-11 (old assume format) and clang-trunk (assume bundles):
#include

That sounds like a bug, yes.
Please file a bug? :)
