    target/i386: unify masking of interrupts
    
    Interrupt handling depends on various flags in env->hflags or env->hflags2,
    and the exact detail were not exactly replicated between x86_cpu_has_work
    and x86_cpu_exec_interrupt.  Create a new function that extracts the
    highest-priority non-masked interrupt, and use it in both functions.

Title:
  BSD bootloader halts with hypervisor.framework

Status in QEMU:
  New

Bug description:
  Guest: FreeBSD 12.0 Install CD
  Host: MacOS 11.14.3 qemu master at 90fb864a7df0a9af677352e94f8225f7b03de922

  Command arguments:

  qemu-system-x86_64 -m 4000m -cdrom Downloads/FreeBSD-12.0-RELEASE-
  amd64-bootonly.iso

  When qemu was run with -accel hvf, the bootloader would halt after
  showing the menu. The bootloader would not respond to any keyboard
  events.

  Without acceleration option, the bootloader would count down to zero
  and proceed.
