A likely consequence of JDK-8213084, CodeStrings passed directly to Disassembler::decode are ignored.

For example, -XX:+PrintInterpreter (on debug builds) included messages which can help in reading the code:

  0x00007f1f7093becb: je 0x00007f1f7093bee5
 ;; call_VM_base: heap base corrupted? <--- gone
  0x00007f1f7093bed1: mov $0x7f1f90c7ecb8,%rdi
  0x00007f1f7093bedb: and $0xfffffffffffffff0,%rsp
  0x00007f1f7093bedf: callq 0x00007f1f9046c0a0 = MacroAssembler::debug64(char*, long, long*)
