>> This patch updates stackMapTableFormat.hpp to handle early_larval frames so they can be correctly printed in the case of verification errors, especially those introduced with the handling of early_larval frames and strict fields. Note that early_larval frames "wrap" normal stack map frames so they are handled differently. Verified with tier 1-5 tests.

Thanks for catching that, I don't like it either. I can just fix all of them in this patch.
