Merge remote-tracking branch 'upstream/master'

Commiting upstream merge (including new struct layout), with a couple
important errata:
  - idump methods need to be disambiguated
  - The first field in a Stream must be a Pointer BitsType (unlike
    upstream where it must be an Array) or the logic in jl_show_* in
    builtins.c must be improved
