Add an option to allow the attribute propagation on the index to be
disabled, to allow a workaround for issues (such as that fixed by
D70977 <https://reviews.llvm.org/D70977>). Restructure the code to include all attribute propagation
handling into propagateAttributes() itself (rather than having some in
the caller), which also simplifies handling of the new option.
