Add a self test to check if FP/VEC/VSX registers are sane (restored correctly) after a FP/VEC/VSX unavailable exception is caught during a transaction.
This test checks all possibilities in a thread regarding the combination of MSR.[FP|VEC] states in a thread and for each scenario raises a FP/VEC/VSX unavailable exception in transactional state, verifying if vs0 and vs32 registers, which are representatives of FP/VEC/VSX reg sets, are not corrupted.
