[Qemu-devel] [RFC PATCH for 2.9] gdbstub: remove spurious tb_flush() calls

[Alex Bennée]

These are (now) mostly harmless but not needed. The correct place to
flush if you want to is in the TCG aware code and not in gdbstub.
Currently flushes are triggered for cpu_single_step() and breakpoint
manipulation.
