target/i386: Tidy hw_breakpoint_remove
...
Since cpu_breakpoint and cpu_watchpoint are in a union,
the code should access only one of them.

target/i386: Use cpu_breakpoint_test in breakpoint_handler
...
The loop is performing a simple boolean test for the existence
of a BP_CPU breakpoint at EIP. Plus it gets the iteration wrong,
if we happen to have a BP_GDB breakpoint at the same address.
We have a function for this: cpu_breakpoint_test.

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.
