This moves building of constant properties and elements arrays for all materialized literals into the compiler. The parser no longer allocates while parsing ObjectLiteral and ArrayLiteral expressions.

* AstNode now has a position info. * 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.

Current v8 implementation may disable optimization for a particular function or block it with help of dont_optimize flag. The patch propagates the reason of that to the SharedFunctionInfo where cpu profiler can get it. SharedFunctionInfo is a heap object so I extracted 8 bits from OptsCount for handling bailout reason code.

In the RegExpUnparser::VisitText(RegExpText* that, void* data) function always RegExpUnparser::VisitAtom function called via that->elements()->at(i).data.u_atom->Accept(this, data); even if the type of the object is RegExpCharacterClass. The problem shows using g++ 4.7(.2, .3) since r16232, since GCC optimizes virtual method calls to direct calls based on __final/final hints. Tested on MIPS and x64: Program received signal SIGSEGV, Segmentation fault. 0x0000000000588928 in v8::internal::RegExpUnparser::VisitAtom(v8::internal::RegExpAtom*, void*) () This cleans up the TextElement class to avoid the unsafe+unchecked union access, that caused the crash.
