#96 and #97 are GATE-BLIND: both stages emit byte-identical asm before
and after the fix, so the 990-997 byte-id gates can never catch a
reintroduction. Only an executed-and-checked runtime probe can. Adds
test/wcc/951_f64cgen_run.c, a table-driven cstage build+run harness
(modeled on 700_e2e) asserting exit codes.
Coverage: #96 f64/f32 deref-load (MOVSD/MOVSS into X0) via bare *p, f64
return through a fn, arith-through-deref, f64frombits reinterpret round
-trip, and copysign-style sign transfer; #97 the full 6-relop NaN sweep
(UCOMISD + UCOMISS), isnan true/false, a NaN-relop true-count value
assert, and the untouched >/>= left-bare arm. Verified the suite fails
on master 0d1ae17 (7/9 rows) and passes on the fix (9/9).
cstage-only by design (mirrors 700_e2e + 969_checked_run): ww_ww run is
broken (#95) and per-program wwstage byte-id is the 990-997 gates' job.
