The runtime and ilc handle setting the thumb bit during compilation/emission of methods. Crossgen does not handle it and instead leaves it to runtime fixup resolution to add the thumb bit. However, crossgen does not emit fixups for resumption stub entrypoints, so calls into the resumption stubs were missing the thumb bit. In #125421, the jit started doing a special case check to add the thumb bit for crossgen2, but we should unify on a single behavior, either emitting the thumb bit into the fixups and relocs in crossgen, or making the resumption stub entrypoint a fixup.
