* egil/fix-hash-float-zero/OTP-12641: erts: Ensure hashing of zero is consistent
2015-04-10erts: Ensure hashing of zero is consistentBjörn-Egil Dahlberg
Erlang treats positive and negative zero as equal, meaning, true = 0.0 =:= 0.0/-1 However, Erlangs hash functions: hash, phash and phash2 did not reflect this behaviour. Meaning, the hash values produced by the different hash functions would not be identical for positive and negative zero. This commit ensures that hash value of positive zero is always produced regardless of the signedness of the zero float, i.e. true = erlang:phash2(0.0) =:= erlang:phash2(0.0/-1)

2015-04-10erts: Fix building of Map result from match_specsBjörn-Egil Dahlberg
A faulty "box-value" entered into the heap which could cause a segmentation fault in the garbage collector if it was written on a heap fragment.

2015-04-09erts: Cover maps:values/1 for large mapsBjörn-Egil Dahlberg
2015-04-09erts: Test maps:from_list/1 shrinkingBjörn-Egil Dahlberg
Repeated keys will shrink map to a flatmap if the number of pairs drops below the limit.

2015-04-08erts: Fix ets bug in debug VMSverker Eriksson
Symptom: ASSERT(segtab[seg_ix] == NULL) in alloc_seg() fails. Remedy: Make sure we set segment pointer to NULL in free_seg() even when we switch to smaller segtab.

2015-04-07erts: Fix bug in map_from_list when keys clash in both value and hashSverker Eriksson
Subtle bug in qsort callback. Cast from Sint to int does not retain sign.
2015-04-07erts: Fix bug in binary_to_term for big maps with 32 bit hash-clashSverker Eriksson
binary_to_term threw badarg as the "reject_dupkey" case in hashmap_from_unsored_array was always triggered when hash-clash was found as the first round in the loop compared the key with itself.

Bail out as soon as we find a diff between maps if we are not interested in term order.
2015-03-30erts: Refactor encode_size_struct_intSverker Eriksson
to handle the "start of list" case in one place and not seven. Note that this commit reverts (47d6fd3ccf35) back to using WSTACK and pushing raw pointers. We disable GC while yielding, so this should not be a problem.
2015-03-30erts: Suppress valgrind for bif_SUITE:erlang_haltSverker Eriksson
which does a deliberate deref of null pointer which is caught by a SEGV signal handler to resume crash dumping.
