Evaluation

This is a bug in the server compiler caused by the special handling of
MemBarAcquire nodes which are used for proper memory syncronization of
volatile loads. Before machine instruction matching, the input to the
MemBarAcquire which is the address of the volatile memory is converted
to a precedence edge to prevent problems with in register allocation.
Fix is a backport from 141, see bug 4701435
