  TableGen: sort SearchableTable emission order by fields, not top-level name

This is often used for anonymous definitions, so we were sorting by
"anonymous_1234" record names, which while less bad than pointers can be easily
perturbed by adding code even in completely unrelated systems. That causes test
failures on AArch64 when sysregs with multiple valid names suddenly start
printing a different one.
