Improve TraceOptoParse to dump the bytecode name

While I was debugging with `TraceOptoParse`, I found it only prints the bci without the bytecode name.
I had to map the bci to the bytecode manually again and again.
It would be better to also dump the bytecode name.

Before:
```
    568 503 4 jdk.internal.org.objectweb.asm.ByteVector::putUTF8 (144 bytes)
Merging state at block #0 bci:0 with empty state on path 1
Parsing block #0 at bci [0,11), successors: 1 2
 @ bci:0
 @ bci:1
Uncommon trap reason='null_check' action='maybe_recompile' debug_id='0' at bci:1
Merging state at block #0 bci:0 with empty state on path 1
Parsing block #0 at bci [0,11), successors:

 @ bci:5
 @ bci:6
Merging state at block #0 bci:0 with empty state on path 1
```

After:
```
