Rename sched_barrier_stalls -> perf_sched_barrier_idles

Sched stall by barrier is really idle because it causes !scheduler_if.valid,

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.

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.
