[lworld] RFR: 8354068: [lworld] Fold strict final fields more aggressively [v3]

[Quan Anh Mai]

> Hi,

> When we do incremental inlining, we need to be more aggressive to ensure that value objects are not unexpectedly materialized. This is done by trying to fold loads from strict final fields in an aggressive manner.

> Please take a look and leave your reviews, thanks a lot.
