929dfd4f59 * infrun.c (displaced_step_fixup): If this is a software
single-stepping arch, don't tell the target to single-step.
	(maybe_software_singlestep): Return 0 if we're using displaced
	stepping.
	(resume): If this is a software single-stepping arch, and
	displaced-stepping is enabled, use it for all single-step
	requests.

c36b740af1 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.
