Revert "Save opline before fallible arg type check in recv_init jit"

This reverts commit b09bddc.

This causes test failures on macos -- presumably the relevant
difference is that it has no global regs. I suspect that this
is related to the fact that SAVE_VALID_OPLINE may use r0 as
a scratch register, which is already in use. Reverting for now.
