RFR: 8190837: BasicType and BasicTypeSize should refer to HotSpot values

[Yasumasa Suenaga]

Hi all,

Enum values in BasicType and BasicTypeSize are declared as const
values. However, it makes error prone when existing enum values
change.
They should refer to HotSpot values via VMStructs.

This issue has been pointed by Jini [1].

I uploaded webrev for this issue. Could you review it?

I cannot access JPRT. So I need a sponsor.


Thanks,

Yasumasa
