Provide minimal register definition defaults for working with servers that implement neither target.xml nor qRegisterInfo packets. This is useful e.g. when interacting with FreeBSD's kernel minimal gdbserver that does not send target.xml but uses the same layout for its supported register subset as GDB. The prerequisite for this is the ability to determine the correct architecture, e.g. from the target executable. Differential Revision: https://reviews.llvm.org/D116896
