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.

a083601e73 Record allocation stack traces 
This is initial implementation of allocation profiler.

Whenever new object allocation is reported to the HeapProfiler and allocation tracking is on we will capture current stack trace, add it to the collection of the allocation traces (a tree) and attribute the allocated size to the top JS function on the stack.

Format of serialized heap snapshot is extended to include information about recorded allocation stack traces.

This patch is r17301 plus a fix for the test crash in debug mode. The test crashed because we were traversing stack trace when just allocated object wasn't completely configured, in particular the map pointer was incorrect. Invalid Map pointer broke heap iteration required to find Code object for a given pc during stack traversal. The solution is to insert free space filler in the newly allocated block just before collecting stack trace.

f2122438e0 Removed long-running obselete test case. 
The test was the 2nd longest-running test case in debug mode, and the
stuff it tests has already been moved long ago to some other place,
which is in turn heavily tested by far simpler and faster things
(%TruncateString etc.).
