target-sparc: Introduce cpu_raise_exception_ra
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.
