a683dde987 Bug 722946 - Add method to HashTable::Enum for inline rekeying; r=luke 
It is possible in several places to have unconstrained client objects as the key
of a HashMap/HashSet. For generational and compacting GC, we will need to move
these objects in memory. This means we will need to remove and re-insert these
keys in a new location, during GC. Because we cannot safely allocate memory for
this, we need a specialized algorithm inside the HashTable itself.

9dcc1e7f14 Bug 689066 - Fix c++11 incompatibility. r=luke. 
IF MoveRef is used in a rvalue position (which is expected), we could end up
in a situation where, without this this, we would try to pass a T& to a move
constructor, which fails. It is not clear if the compiler should instead use
the copy constructor, but for now this lets us build with clang. See bug
689066 and llvm.org/pr11003 for the details.

e0fa025e18 Bug 657384: Change new_ parameters to pass-by-copy, not pass-by-const-reference. (r=luke) 
new_ [1] took a const reference for each of its parameters. Unfortunately, that
adds const-ness even when the constructor needs non-constness. Unfortunately,
the other way (turning off constness) can lead to excess copying.

According to the Forwarding Problem [2], there is no great solution here. C++
does not have a perfect way to write a function which wraps another function.
So we settle for non-constness, and we must rely on forbidding copying of
expensive objects.

43b850291d Bug 643548: Remove mozalloc_undef_macro_wrappers hack from JS engine. (r=luke,rs=brendan) 
mozalloc_undef_macro_wrappers are brittle and have side-effects that are hard
to debug and fix. The alternative is the just stick an underscore on the end of
malloc, free, etc, which is a comparatively small burden.

72c7701093 Bug 634155: Account for NewCompartment's memory, and change allocation APIs (r=nnethercote) 
This changes the allocation API, in the following way:

  js_malloc -> {cx->,rt->,OffTheBooks::}malloc
  js_calloc -> {cx->,rt->,OffTheBooks::}calloc
  js_realloc -> {cx->,rt->,OffTheBooks::}realloc
  js_free -> {cx->,rt->,Foreground::,UnwantedForeground::}free
  js_new -> {cx->,rt->,OffTheBooks::}new_
  js_new_array -> {cx->,rt->,OffTheBooks::}new_array
  js_delete -> {cx->,rt->,Foreground::,UnwantedForeground::}delete_

This is to move as many allocations as possible through a JSContext (so that they may be aken into account by gcMallocBytes) and to move as many deallocations to the background as possible (except on error paths).
