move use of SingleRead::successor; fix build errors
...
We now use SingleRead::successor in pickTarget, where we use it to
determine the prefered target site for the successor without requiring
the target to conform to that preference. The previous code made the
preference a hard requirement, which is not desirable or even possible
in general.

add SingleRead::successor; fix build errors
...
The SingleRead::successor field is used (when non-null) to further
constrain the SiteMask in SingleRead::intersect based on reads of
successor values (as in the cases of moves and condensed-addressing
combine and translate instructions).

This is important on the 32-bit OS X PowerPC ABI, since the location
of the low 32-bits of a return value change depending on whether the
entire value is 64-bits or not.

remove the libstdc++ dependency once and for all
...
The trick is to make all destructors non-virtual. This is safe because
we never use the delete operator, which is the only case where virtual
destructors are relevant. This is a better solution than implementing
our own delete operator, because we want libraries loaded at runtime to
use the libstdc++ version, not ours.
