      [release-branch.go1.8] all: final merge of master into Go 1.8 release branch · d8d2f036
      Russ Cox authored
      After this, we will merge some of the dev work like
      type aliases and inlining into master, so any additional
      changes for the Go 1.8 release will need to be cherry-picked,
      not merged.

      runtime: amd64, use 4-byte ops for memmove of 4 bytes · a96e117a
      Keith Randall authored
      memmove used to use 2 2-byte load/store pairs to move 4 bytes.
      When the result is loaded with a single 4-byte load, it caused
      a store to load fowarding stall.  To avoid the stall,
      special case memmove to use 4 byte ops for the 4 byte copy case.
      
      We already have a special case for 8-byte copies.
      386 already specializes 4-byte copies.
      I'll do 2-byte copies also, but not for 1.8.

      3-byte copies get a bit slower.  Other copies are unchanged.
