This doubles the size of `Qualifiers` which is passed by value all over the
place. I don't expect significant performance issues from this (though we do
still support 32-bit builds of Clang), but do you have ideas on how this
impacts compile time performance and memory pressure? (Changes in the type
system can have outsized impact in surprising places.)
It may be worth putting a branch up on https://llvm-compile-time-tracker.com/
to see how this impacts things.
