I see failures with TestJlmRemote* in sanity.system on macOS. They are SEGVs in resolveStaticSplitMethodRef and resolveSpecialSplitMethodRef.

Enabling the SVM results in us executing more code paths under a relocatable compilation than before. This is because we no longer have to pretend that things are unresolved. However, the consequence of this is that there may be additional relocation records needed (e.g. resolved direct call snippet). #3028 goes over a few of the things that have be taken into account before the SVM can be enabled on a platform.

As such, I think specifically for #15059, the solution should be what @jdmpapin suggested, namely setting TR_DisableKnownObjectTable if we're doing a relocatable compile. Enabling the SVM is a useful effort but I believe it's going to require some vetting first.

Issue #15059 has been fixed by PR #15131 following the suggestion above.
I will revisit this PR sometime later for enabling SVM on AArch64.

I will not be working on this one soon. Closing.
