Review Comment:
Thanks @jpountz. This is a good suggestion, and I missed that while making
the changes. But when I started using it, I was curious about the
implementation and saw that it initializes reference for all the Enum values
during initialization:
```
public EnumMap(Class<K> keyType) {
this.keyType = keyType;
keyUniverse = getKeyUniverse(keyType);
vals = new Object[keyUniverse.length];
}
```
Since we are using small subset of `QueryProfilerTimingType`, I am wondering
if this is a good idea. We can also consider separating
`QueryProfilerTimingType` on the basis of slice level or query level.
