move some math ops back to full jit (#40149)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/40149
Many math ops are moved to lite interpreter in D21992552, but some ops (like log) also have tensor version and we didn't check duplicated names in this case. This breaks some existing models.
Move back most ops for now until we have a cleaner solution
Test Plan: build
