RFR: 8298091: Dump native instruction along with nmethod name when using Compiler.codelist

[Yi Yang]

Dump native instruction along with nmethod name when using Compiler.codelist.

e.g.
jcmd <pid> Compiler.codelist decode=<method_name>

Output:
<compile_id> <compile_level> <state> nmethod_name [addr_begin, code_begin, code_end]
<native instruction>
