The adaptations look good! @TobiHartmann additionally submitted some testing.

I've just seen that [TestUnloadedInlineTypeField](https://github.com/openjdk/valhalla/blob/lworld/test/hotspot/jtreg/compiler/valhalla/inlinetypes/TestUnloadedInlineTypeField.java) is not enabled for aarch64. Was that one missed?

test/hotspot/jtreg/compiler/valhalla/inlinetypes/InlineTypes.java line 117:

Just about the variable name: Shouldn't this be `MYVALUE_ARRAY_KLASS`?

test/hotspot/jtreg/compiler/valhalla/inlinetypes/InlineTypes.java line 146:

`CLFI` and `CLR` is only used for s390 and PPC, respectively. But I guess it does not hurt to keep it that way.
