06e58a92ae Bug 1038601 - Shrink js::HashTable. r=luke. 
This patch reduces sizeof(js::HashTable):
- On 64-bit: from 32 bytes to 24 bytes.
- On 32-bit: from 24 bytes to 16 bytes.

The latter is particularly nice because jemalloc rounds up allocation requests
of 24 bytes to 32, but it can allocate 16 bytes without slop, so we're saving
16 bytes per heap-allocated HashTable.

This is done by:
- Shrinking |removedCount| and |hashShift|.
- Reordering the fields.
- Not defining |mutationCount| and |mEntered| in non-DEBUG builds rather than
  using DebugOnly<> -- in non-DEBUG builds, DebugOnly<> fields take up 1 byte
  each.

This change saves over 55 KiB when starting Firefox and loading Gmail.

The patch also uses uint32_t more consistently for the generation.

00dd69c3f8 Bug 645416, part 21 - Add symbol jsids (SYMBOL_TO_JSID), removing the legacy support for object jsids (OBJECT_TO_JSID). r=terrence,r=jimb,r=efaust. 
With just this patch, there are not actually any symbol jsids flowing through
the system, just as there are not actually any object jsids. But a subsequent
patch (part 23) changes this.

This patch deletes some code in CTypes.cpp that is simply confused about how
element accesses work: Int64 and UInt64 objects were never actually converted
to object jsids, so the code being removed here was already dead code.

42a78a347e Bug 645416, part 3 - Symbol layout and GC support for allocating them. r=terrence. 
Layout: js/src/vm/Symbol.h defines the new class JS::Symbol. JS::Symbol is the
same size as JSString on all platforms, because the allocator does not support
smaller allocations.

Allocation: Since the purpose of symbols is to serve as property keys, they are
always allocated in the atoms compartment.

We take a lock when allocating. This could probably be replaced with a
main-thread-only assertion. However, if atom allocation is not already a
bottleneck, symbol allocation probably never will be.

Symbols are given their own finalize-class in the GC. This means we allocate a
page per zone for symbols, even though they are only ever allocated in the
atoms zone. Terrence thought this could be easily fixed later. It should be; we
never touch the page, but a 32-bit virtual address space does not just have
infinite pages to spare.

A jsapi-test exercises the new symbol allocation code. A few oddities in
jsapi-tests are fixed in passing.

Discussion after review led to some new assertions about minimum object size in
AllocateObject and AllocateNonObject.
