Stevie Strickland 38829df284 [VM/Compiler] Fix binds replaced with statements. ...

In some cases, we could replace a binding instruction like a
InstanceCall with a subgraph that would end with a non-binding
instruction like a StoreInstanceFieldExpr.  When the inliner attempted
to replace the uses of the former, the lack of an SSA temp in the latter
would cause weird results.

Change the code to check that the new replacement has an SSA temp, and
if it doesn't, use the temp assigned to the null constant in the flow
graph.
