Alex Bennée b29fd33db5 target/arm: use DISAS_EXIT for eret handling ... Previously DISAS_JUMP did ensure this but with the optimisation of 8a6b28c7 (optimize indirect branches) we might not leave the loop. This means if any pending interrupts are cleared by changing IRQ flags we might never get around to servicing them. You usually notice this by seeing the lookup_tb_ptr() helper gainfully chaining TBs together while cpu->interrupt_request remains high and the exit_request has not been set. This breaks amongst other things the OPTEE test suite which executes an eret from the secure world after a non-secure world IRQ has gone pending which then never gets serviced. Instead of using the previously implied semantics of DISAS_JUMP we use DISAS_EXIT which will always exit the run-loop.
