qemu-system-x86_64: stuck on watchpoint hit
Description of problem:
Steps to reproduce:
1. `gcc -O0 -g watch-bug.c -o watch-bug`
2. `gdb watch-bug`
3. gdb commands:
```
b main
r
watch l1
next [ correct stop on the next line ]
next [ qemu is stuck as watchpoint should be hit ]
```
Additional information:
* NOTE: it works correctly, if 'continue' command is used instead of 'next'
`watch-bug.c`
```c
int i0;
long l1;
int main(int argc, char* argv[])
{
i0 = argc;
l1 = i0 * 7;
return 0;
