Update to:

The patch (the removal) was done on the wrong assumption that
it was only the APX-promoted forms which would be dropped
because the APX spec was updated ahead of ISE and there is no info
that AMX-TRANSPOSE would be de-published. Given the current
situation, since we will choose to disable AMX-TRANSPOSE but not
to remove the support in Binutils, we will also not remove the
APX support.

Thx,
