Merge branch 'bjorn/maps'

* bjorn/maps:
  Document the new {badmap,Term} and {badkey,Key} exceptions
  Raise more descriptive error messages for failed map operations
  erl_term.h: Add is_not_map() macro
  Tigthen code for the i_get_map_elements/3 instruction
  Pre-compute hash values for the general get_map_elements instruction
  Teach the loader to pre-compute the hash value for single-key lookups
  Optimize use of i_get_map_element/4
  beam_emu: Slightly optimize update_map_{assoc,exact}
  v3_codegen: Don't sort map keys in map creation/update
  beam_validator: No longer require strict literal term order
  Sort maps keys in the loader
  De-optimize the has_map_fields instructions
  erts/map_SUITE.erl: Add a test case that tests has_map_fields
  Fully evaluate is_map/1 for literals at load-time
  map_SUITE: Add tests of is_map/1 with literal maps
  Run a clone of map_SUITE without optimizations
  Remove the fail label operand of the new_map instruction
  Correct transformation of put_map_assoc to new_map
  Remove support for put_map_exact without a source map
