dba72409aa 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.

35d1c6e068 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).

fea92ed995 more work on tail recursion 
We now create a unique thunk for each vtable position so as to avoid
relying on using the return address to determine what method is to be
compiled and invoked, since we will not have the correct return address
in the case of a tail call.  This required refactoring how executable
memory is allocated in order to keep AOT compilation working.  Also, we
must always use the same register to hold the class pointer when
compiling virtual calls, and ensure that the pointer stays there until
the call instruction is executed so we know where to find it in the
thunk.
