    cmd/internal/obj: drop Addr's Gotype field · 7124056f
    Matthew Dempsky authored
    The Gotype field is only used for ATYPE instructions. Instead of
    specially storing the Go type symbol in From.Gotype, just store it in
    To.Sym like any other 2-argument instruction would.
    
    Modest reduction in allocations:
    
    name       old alloc/op    new alloc/op    delta
    Template      42.0MB ± 0%     41.8MB ± 0%  -0.40%         (p=0.000 n=9+10)
    Unicode       34.3MB ± 0%     34.1MB ± 0%  -0.48%         (p=0.000 n=9+10)
    GoTypes        122MB ± 0%      122MB ± 0%  -0.14%         (p=0.000 n=9+10)

    Passes toolstash -cmp.
