AMD IBS OP_DATA2 and OP_DATA3 provides detail about tagged load/store
ops. Add definitions for these registers into header file. In addition
to those, IBS_OP_DATA2 DataSrc provides detail about location of the
data being accessed from by load ops. Define macros for legacy and
extended DataSrc values.
