Commit 5459 broke gdbstub's dynamic register set switching between
x86-64 and i386. That prevents setting the correct architecture in gdb
when debugging 32 or 16-bit code in a 64-bit emulator. This patch
reintroduces the feature over previous refactorings.

How does this interact with SMP? If you have one VCPU in 32-bit mode and another in 64-bit mode, won't that confuse GDB?
