This patch enables reverse debugging with watchpoints.
Reverse continue scans the execution to find the breakpoints
and watchpoints that should fire. It uses helper function
replay_breakpoint() for that. But this function needs to access
icount, which can't be correct in the middle of TB.
Therefore, in case of watchpoint, we have to retranslate the block
to allow this access.
