Eli Friedman 202bb919c0 Make Value::getPointerAlignment() return an Align, not a MaybeAlign. ... If we don't know anything about the alignment of a pointer, Align(1) is still correct: all pointers are at least 1-byte aligned. Included in this patch is a bugfix for an issue discovered during this cleanup: pointers with "dereferenceable" attributes/metadata were assumed to be aligned according to the type of the pointer. This wasn't intentional, as far as I can tell, so Loads.cpp was fixed to stop making this assumption. Frontends may need to be updated. I updated clang's handling of C++ references, and added a release note for this. Differential Revision: https://reviews.llvm.org/D80072		2020-05-20 16:37:20 -07:00
