50263a5f7d Rename sched_barrier_stalls -> perf_sched_barrier_idles
Sched stall by barrier is really idle because it causes !scheduler_if.valid,
which is counted as part of sched_idle.

bd67ff3439 Fix creating bogus mem reqs when commit is stalled
When commit stage is stalled, LSU ready is deasserted for mem writes
since stores commit immediately; however, the same was not applied to
valid, creating duplicate memory write requests.  Fix by guarding both
ready and valid properly.

8317a3fbe5 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.

This reverts commit a15f4fd483.

a15f4fd483 [BUGFIX] Set mem_req_mask to 0 for fence
Fence instructions have address field set to X's which propagates to
cache_req_ready, causing issue stalls.  Fix this by setting req_mask to all-zero
so that they can be handled unaffected by x-propagation.

Setting req_valid to 0 does not fix the problem because the LSU only commits
instructions when they have a matching response coming back.
