Several of the TM tests fail spuriously if CPU 0 is offline, because
they blindly try to affinitise to CPU 0.
Fix them by picking any online CPU and using that instead.

Some processor revisions do not support transactional memory, and
additionally kernel support can be disabled. In either case the
tm-trap test should be skipped, otherwise it will fail with a SIGILL.

Add a selftest to check if endianness is flipped inadvertently to BE
(MSR.LE set to zero) on BE and LE machines when a trap is caught in
transactional mode and load_fp and load_vec are zero, i.e. when MSR.FP
and MSR.VEC are zeroed (disabled).
