VecElem code had been introduced in order to simulate change of renaming
for vector registers. Most of the work is happening on the rename_map
switchRenameMode. Change of renaming can happen after a squash in the
pipeline.
This patch is also changing the interface to the ISA part so that
a PCState is used instead of ISA in order to check if rename mode
has changed.
