For builtin and stub code targets, we can be a bit more descriptive and
print their name along with the code kind.

Before:
0x1fafde09c5cf  code target (BUILTIN)  (0x1fafde088280)
0x1fafde09c5f0  code target (STUB)  (0x1fafde084060)

After:
0x1fafde09c5cf  code target (BUILTIN Abort)  (0x1fafde088280)
0x1fafde09c5f0  code target (STUB CEntryStub)  (0x1fafde084060)
