gdb, breakpoint: add breakpoint location debugging logs
Add new commands:
set debug breakpoint on|off
show debug breakpoint
This patch introduces new debugging information that prints
breakpoint location insertion and removal flow.
The debug output looks like:
~~~
(gdb) set debug breakpoint on
(gdb) disassemble main
Dump of assembler code for function main:
0x0000555555555129 <+0>: endbr64
0x000055555555512d <+4>: push %rbp
0x000055555555512e <+5>: mov %rsp,%rbp
=> 0x0000555555555131 <+8>: mov $0x0,%eax
0x0000555555555136 <+13>: pop %rbp
0x0000555555555137 <+14>: ret
End of assembler dump.
(gdb) break *0x0000555555555137
Breakpoint 2 at 0x555555555137: file main.c, line 4.
[breakpoint] update_global_location_list: insert_mode = UGLL_MAY_INSERT

Continuing.
