This revision is now accepted and ready to land.

Using `x31` is confusing and not compatible with the GNU assembler, which are both god reasons to reject it. Also, the only occurrence of `x31` in the architecture manual is this:

> There is no register named W31 <https://reviews.llvm.org/W31> or X31.
