arguments. * Adds 'nonnull' and 'dereferenceable(N)' to 'this' pointer arguments * Gates 'nonnull' on -f(no-)delete-null-pointer-checks * Introduces this-nonnull.cpp and microsoft-abi-this-nullable.cpp tests to explicitly test the behavior of this change * Refactors hundreds of over-constrained clang tests to permit these attributes, where needed * Updates Clang12 patch notes mentioning this change Reviewed-by: rsmith, jdoerfert Differential Revision: https://reviews.llvm.org/D17993
