[PULL 18/18] target/s390x: Exit tb after executing ex_value

[Thomas Huth]

From: Richard Henderson <richard.henderson@linaro.org>

When EXECUTE sets ex_value to interrupt the constructed instruction,
we implicitly disable interrupts so that the value is not corrupted.
Exit to the main loop after execution, so that we re-evaluate any
pending interrupts.
