Paolo Bonzini 533883fd7e target/i386: fix exceptions for MOV to DR
Use raise_exception_ra (without error code) when raising the illegal
opcode operation; raise #GP when setting bits 63:32 of DR6 or DR7.

Move helper_get_dr to sysemu/ since it is a privileged instruction
that is not needed on user-mode emulators.
