[jdk8u-dev] RFR: 8250825: C2 crashes with assert(field != __null) failed: missing field

[SendaoYan]

Hi all,
This is backport of [JDK-8250825](https://bugs.openjdk.org/browse/JDK-8250825).
Patch does not apply cleanly due to different context, before [JDK-8250825](https://bugs.openjdk.org/browse/JDK-8250825)  the  PR [JDK-8230505](https://bugs.openjdk.org/browse/JDK-8230505) change these lines, and I think [JDK-8230505](https://bugs.openjdk.org/browse/JDK-8230505) do not needed backport to jdk8u-dev.

New test fails without the patch, passes with it.

Additional testing:

- [ ] linux x64 tier1/2/3 jtreg test
- [ ] inux aarch64 tier1/2/3 jtreg test
