[PATCH 00/12] Use intrusive_list for breakpoints and breakpoint locations

[Simon Marchi]

This series changes two linked lists to use intrusive_list.  There are
some cleanups before that, and some small fixes that needed to be made
to some of our iterator wrappers.

Simon Marchi (12):
  gdb: get gdbarch from syscall_catchpoint instead of location
  gdb: make some breakpoint methods use `this`
  gdb: constify breakpoint::print_it parameter
  gdb: add breakpoint "has locations" methods
  gdb: add breakpoint::first_loc methods
  gdbsupport: add missing increment/decrement operators to
    reference_to_pointer_iterator
  gdb: link breakpoint locations with intrusive_list
  gdb: remove bp_location_pointer_iterator
  gdb: link breakpoints with intrusive_list
  gdbsupport: make basic_safe_iterator::operator* return the same thing
    as underlying iterator
  gdbsupport: make filtered_iterator::operator* return the same thing as
    underlying iterator
  gdb: remove breakpoint_pointer_iterator
