Stop infrun from tracking breakpoint insertion status.
The checks of breakpoints_inserted before calling
remove_breakpoints are removed, as remove_breakpoint
won't touch uninserted breakpoints. In a number of places,
we're interested if a breakpoint is inserted at particular
PC, and we now use breakpoint_inserted_here_p. In a few
places, insert_breakpoints can be called unconditionally,
since it won't try to insert already inserted breakpoint.
