Add dummy code for decoupled Hopper tensor core
...
Define EXT_T_HOPPER that, when EXT_T_ENABLE is defined, distinguishes
whether to instantiate core-coupled Volta-style or decoupled
Hopper-style Tensor Core.

tensor: Decode rd of macro-op to designate additional accumulator
...
This is useful when you want to have the tensor core output to multiple
accumulator registers, e.g. when doing outer product within the RF.

Fix fence by disallowing x-initialization instead of all-0 mask
...
Setting mem_req_mask to all-zero triggers an assertion error in
mem_scheduler. Instead, disallow initialize-by-x in instruction decode
which is the source of x-propagation. Since this seems to only happen
in VCS, define-gate it accordingly.
