This reverts commit r17365 for memory corruption. The issues
are most probably related to storing a filler map without
checking the bump pointer first, and traversing the stack
when called from within a stub (or builtin), while the code
assumes that it's called from a JS function.

It is very hard to understand the structure of the heap even for about:blank page
because code objects in the heap have no names. This patch propagates the names
for Code::STUB and Code::BUILTIN code objects.
Also it assign function names from SharedFunctionInfo to the code objects.

When --optimize-for-size is true, the prologue generation outputs the
pre-aging code stub address directly to the instruction stream.  Previously
this was done using dd() which failed if there was any pending constant
pool entries left to be written.  This CL introduces an emit_code_stub_address()
for this purpose instead.

This change enforces explicit allocation of the initial map for each
JSFunction to introduce a proper layering between the JSFunction class
and the Heap class. A follow-up change will then handlify the two
functions AllocateInitialMap and AllocateFunctionPrototype.

This includes handlifing:
-SetHiddenPropertiesHashTable
-ObjectHashSet::Add/Remove
-ObjectHashTable::Put

And splitting the following methods which previously took "allow creation" enum arguments to into side-effect-free getters and GetOrCreate*-handlfied getters.

-GetHash (now GetHash & handlified GetOrCreateHash)
-GetIdentityHash (now GetIdentityHash & handlified GetOrCreateIdentityHash)
-GetHiddenPropertiesHashTable (now GetHiddenPropertiesHashTable & handlified GetOrCreateaHiddenPropertiesHashTable)

To keep the structure of the serializer more or less untouched, we use
some ingenious Corry-approved(TM) 3-step technology (a.k.a. "hack"):

   * Create copies of code objects.
   * Wipe out all absolute addresses in these copies.
   * Write out the cleaned copies instead of the originals.

In conjunction with --random-seed, our snapshots are reproducible now.

This pure refactoring is needed for another upcoming CL.

Note that the actual names are still a bit confusing, because this is
still a kind of swiss-army-knife-field. :-/

Previously, the result of target_reference_address() could only be
read, writing to it would have had an architecture-dependent effect,
e.g. writing into the code on ia32, a no-op on arm, etc.

This refactoring-only CL turns this into a simple getter, making it
impossible to use incorrectly.
