  [LoopFusion] Drop duplicate write-write dependence check (NFC) (#203173)

`dependencesAllowFusion()` re-tested every FC0-write vs FC1-write pair
in the second loop nest, duplicating the checks already done in the
first. Iterate only the remaining FC0-read vs FC1-write pairs; the set
of checked dependences (W0xW1, W0xR1, R0xW1) is unchanged.
