b8660f2091 Revert "Record allocation stack traces". 
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.

a4b4cfdc58 HeapProfiler: provide human readable names for code objects. 
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.

6069b062ae Avoid using dd() in Prologue when --optimize-for-size. 
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.

5267d7b884 Introduce JSFunction::EnsureHasInitialMap method. 
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.

dc8c314084 Make snapshots reproducible. 
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.

d1de1f9808 Refactored EXTERNAL_REFERENCE handling. 
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.

More to come...

5b5f2e59dc Return early from BinaryOpIC::Transition when the JS call failed 
This avoids an ASSERT failure in Chromium net_unittests.

3399bdd289 Temporarily disable calls to OS::TotalPhysicalMemory to avoid ASSERT when running under the Chrome Sandbox. 
This CL reverts the behaviour added in r16983 to avoid calling OS::TotalPhysicalMemory
which fails an assert in the Chrome Sandbox.  It reverts the default
ResourceConstraints behaviour to that of V8 before r16983 (i.e., baseing these
values purely on hard-coded checks against 64bit/32bit and Android/non-Android.
This will be reverted once http://crbug.com/312241 has been resolved.
