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.

5074ecf13b Tune cctest/test-parsing/ParserSync. 
This test suffers heavily from combinatorial explosion. To redemedy
this situation a bit, two independent parsing flags are tested
separately, reducing the runtime by a factor of 4. Furthermore, the
code has been cleaned up a bit.

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.

bdeaf7514a Enable preaging of code objects when --optimize-for-size. 
This change means that code which is never executed is garbage collected immediately, and code which is only executed once is collected more quickly (limiting heap growth), however, code which is re-executed is  reset to the young age, thus being kept around for the same number of GC generations as currently.

* Removed various ad-hoc position infos from subclasses (most of which had it).
* Position is always set with the constructor, instead of later.
* Take care to use kNoPosition in the right spots, to not crash the debugger.

Still to do:

* Eliminate Conditional::then/else_position and WhileStatement::condition_position.
* Make CaseClause a proper AstNode and eliminate its custom position.
* If possible, eliminate all uses of kNoPosition.

doNotCache is true. As a result, Function::New always returns null

bf345f022e Revert "Add flags to force or prevent setting of isolate.is_memory_constrained."
