The blacklisting of bitswap was removed, because we now bailout 
on bit-level operations on 32bit values.

However I did have to add a unittest-specific bailout for 
fail_compilation/fail14304.d
which requires the ctfe interpeter to detect a semantically 
invalid situation that should have been detected before we ever 
begin ctfe.
