Backport of #90650 to release/8.0

/cc @mikem8361

Customer Impact

The SOS command !gcroot on in a simple customer suppled test app SEGSIGV's in the DAC making the command useless.

Testing

Manually with the customer's test app

Risk

Low. Only affects arm32/arm64 DAC.

Faulted in DAC because the HelperMethodFrame's REGDISPLAY CurrentContextPointers were not initialized correctly.

Fixes issue dotnet/diagnostics#3726

Another question, @mikem8361: Did you intend to send it to the release/8.0 branch? Asking because it means it would go to RC2, not RC1.

  • If that is expected, then we only need @jeffschwMSFT approval.

  • If not, then please retarget the PR to the release/8.0-rc1 branch (you can do it by editing the PR title), and fill out the template with the info requested yesterday in my RC2 snap email, then please send an email to Tactics requesting approval.

RC2 (release/8.0) was what I intended so I wouldn't have to go through any more hoops.
