32938e127f target-i386: Fix jmp im on x86_64 when executing 32-bit code 
When running grub-install (32-bit) on an x86_64 Linux system in qemu, it
hangs on a pagefault forever, because an integer overflow occurs on the
IP on "jmp im". This patch masks overflows for 32 bit IPs on a 64 bit
system, just like it is done for 16 bit IPs already.

Using this patch, x86_64 openSUSE installation works again.

c0ce998e94 Use sys-queue.h for break/watchpoint managment (Jan Kiszka) 
This switches cpu_break/watchpoint_* to TAILQ wrappers, simplifying the
code and also fixing a use after release issue in

a1d1bb3101 Refactor and enhance break/watchpoint API (Jan Kiszka) 
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.

First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.

Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.
