While looking at the watchpoint code, I realised that AArch64, ARM, and Loongarch all override watchpoint_addr_within_range with an implementation that is the same as the default (but with the logic written slightly differently). Compare the deleted functions to default_watchpoint_addr_within_range in target.c. The only other targets that override watchpoint_addr_within_range are ppc_linux_nat_target and remote_target, in both cases the implementation is different to the default. Lets remove these unnecessary overrides, and just use the default. There should be no user visible changes after this commit. Approved-By: Simon Marchi <simon.marchi@efficios.com>
