* Profile all stages * Try to recover senders with 8 goroutines * fix CPU profiling for stage_bodies * fix out-of-index * Try full DAG for verfication of header seals * Try to unroll fnvHash for performance * SSE2 assembly for fnvHash16 * fnvHash16AVX2 * Revert changes to state.go * check we're on 64-bit in useAVX2 * Shave a move off fnvHash16AVX2 * asmdecl doesn't know about VMOVD * disable linter in the right place
