target_reg_t is the normal register. target_fpreg_t is the floating
point registers. target_copy_regs copies the registers out of CPU
context for things like core dumps.

While this mirrors what linux-user does, I've wondered if this wasn't just pointless
copying. If a bit of code knows enough about a target to fill in its core dump, why
wouldn't it just copy the data straight from CPUArchState instead of using these
intermediaries?
