975db45e9c locking/static_keys: Avoid nested functions 
clang does not support nested functions inside of an array definition:

  lib/test_static_keys.c:105:16: error: function definition is not allowed here
                          .test_key       = test_key_func(&old_true_key, static_key_true),
  lib/test_static_keys.c:50:20: note: expanded from macro 'test_key_func'
          ({bool func(void) { return branch(key); } func; })

That code appears to be a little too clever, so this simplifies it
a bit by defining functions outside of the array.

2bf9e0ab08 locking/static_keys: Provide a selftest 
The 'jump label' self-test is in reality testing static keys - rename things
accordingly.

Also prettify the code in various places while at it.
