If a user does a function call from GDB, or tells GDB to return from a
function, and BNDPRESERVE is zero, will it act as a BND-prefixed branch
that preserves the bounds registers or as a non-BND-prefixed branch that
clears the bounds registers? (It's not obvious that there is one answer
that's best in all circumstances.)
