Several helpers call helper_raise_exception directly, which requires in turn that their callers have performed save_state. The new function allows a TCG return address to be passed in so that we can restore PC + NPC + flags data from that. This fixes a bug in the usage of helper_check_align, whose callers had not been calling save_state. It fixes another bug in which the divide helpers used GETPC at a level other than the direct callee from TCG. This allows the translator to avoid save_state prior to SAVE, RESTORE, and FLUSHW instructions.
