Backport of #109524 to release/9.0-staging

/cc @jkotas

Customer Impact

  • Customer reported
  • Found internally

Runtime crash when Assembly.Load or other APIs that requires stackwalk to find the calling method gets called from a method that uses stackalloc.

Regression

  • Yes
  • No

.NET 8 -> .NET 9 regression introduced by #99137 (runtime simplification)

Testing

Regression test added

Risk

Low. The fix is suppressing superfluous sanity checks.

LightUnwind does not track sufficient context to compute GS cookie address

Fixes #109242
