[PATCH v2 05/15] target/i386: Constify CPU*State for cpu_*_interrupt() getters

["Philippe Mathieu-Daudé" <philmd@oss.qualcomm.com>]

x86_cpu_pending_interrupt() and x86_cpu_interrupts_enabled()
only read CPU state without modification, add the const
qualifiers to CPUState and CPUX86State parameters.
Simplify directly using cpu_env() in x86_cpu_pending_interrupt.
