Fix leaks by clearing registers and frame caches.
Valgrind reports leaks such as the below in the tests: gdb.threads/corethreads.exp gdb.threads/gcore-thread.exp gdb.ada/task_switch_in_core.exp gdb.trace/tfile.exp gdb.base/siginfo-thread.exp ==12701== 1,123 (72 direct, 1,051 indirect) bytes in 1 blocks are definitely lost in loss record 2,928 of 3,247 ==12701== at 0x4C2C4CC: operator new(unsigned long) (vg_replace_malloc.c:344) ==12701== by 0x5CF771: get_thread_arch_aspace_regcache(ptid_t, gdbarch*, address_space*) (regcache.c:330) ==12701== by 0x5CF92A: get_thread_regcache (regcache.c:366) ==12701== by 0x5CF92A: get_current_regcache() (regcache.c:372) ==12701== by 0x4C7964: get_current_frame() (frame.c:1587) ==12701== by 0x4C7A3C: get_selected_frame(char const*) (frame.c:1651) ==12701== by 0x669EAD: print_thread_info_1(ui_out*, char const*, int, int, int) (thread.c:1151) ==12701== by 0x66A9A1: info_threads_command(char const*, int) (thread.c:1217) ==12701== by 0x40A878: cmd_func(cmd_list_element*, char const*, int) (cli-decode.c:1892) ... Fix these leaks by clearing registers and frame caches. This leak and fix is similar to the leak fixed by 799efbe8e01
