Such variables (across the whole patch) should be really renamed when changing
its type.

I understand there are already cases of such incorrect naming in GDB but we
should not make it worse.

Also were these functions intended per-breakpoint or per-bp_location?
It looks to me currently they are used only for single-location breakpoint so
no one knows.  (I guess they were meant for breakpoint.)

At least rename it to insert_bploc (or insert_location etc.).  This will need
to be cleaned up with the regular breakpoints/watchpoints conversion to
breakpoint_ops.
