QEMU cannot pass through the breakpoints when 'si' command is used in remote gdb. This patch disables inserting the breakpoints when we are already single stepping though the gdb remote protocol. This patch also fixes icount calculation for the blocks that include breakpoints - instruction with breakpoint is not executed and shouldn't be used in icount calculation.
