JIT assert on arm32 when running DllImportGenerator unit tests: remainingSize == 4 #60705
Description
I just hit this on CI on a coreclr checked alpine 3.14 arm and Linux arm runs
net7.0-Linux-Debug-arm-CoreCLR_checked-(Alpine.314.Arm32.Open)

DllImportGenerator.UnitTests.IncrementalGenerationTests.AppendingUnrelatedSource_DoesNotRegenerateSource [SKIP]
The GeneratorDriver treats all SyntaxTree replace operations on a Compilation as an Add/Remove operation instead of a Modify operation, so all cached results based on that input are thrown out. As a result, we cannot validate that unrelated changes within the same SyntaxTree do not cause regeneration.
