We aren't doing anything with vxsat right now, but I'd like to add it as
an accepted register to the clobber list. If we get this into GCC-14
then we'll avoid some preprocessor-based twiddling if we ever start
using vxsat in the future.
gcc/ChangeLog:
* config/riscv/riscv.h (REGISTER_NAMES): Add vxsat.

IIUC we aren't using these N/A regnos for anything, they're just there to pad
out the types. So I think this is safe, but Juzhe would likely know best here.
See
https://inbox.sourceware.org/libc-alpha/[email protected]/
a use of this.
