x86: avoid AREG0 for exceptions
Add an explicit CPUX86State parameter instead of relying on AREG0. Merge raise_exception_env() to raise_exception(), likewise with raise_exception_err_env() and raise_exception_err(). Introduce cpu_svm_check_intercept_param() and cpu_vmexit() as wrappers. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
