Arithmetic right shifting is *not* division in two's complement representation, only in one's complement. So we convert to one's complement, shift, and go back to two's complement. By permutating the last steps, one can get efficient branch-free code. This insight comes from the paleozoic era of computer science, see the paper from 1976: Guy Lewis Steele Jr.: "Arithmetic Shifting Considered Harmful" ftp://publications.ai.mit.edu/ai-publications/pdf/AIM-378.pdf This results in better and more correct code than our previous "neg/shift/neg" dance.

Notes: - We use simple recursion to keep track of how many "new" operators we have seen and where. - This makes the self-baked stack class PositionStack in parser.cc unnecessary. - Now the logic is also unified between Parser and PreParser. - This is a fixed version of r19386.

It turned out that JSArrayBuffer's may share their backing_store so the backing_store should go through hash map registration just like other heap objects, so they won't be reported twice.

Added support for truncating DoubleToIStub and reorganize the macro-assembler dToI operations to do the fast-path inline and the slow path by calling the stub.

Use a dedicated BuildLoadNamedField() with PropertyAccessInfo, similar to BuildStoreNamedField() for optimized graph building, and a dedicated BuildLoadNamedField() for the code stubs, and don't depend on FLAG_track_double_fields during code generation.

This addresses several TODOs: - Push and Pop requests can be queued up so that arrays of Registers can be pushed efficiently, with just one PrepareForPush/Pop. - PushMultipleTimes now takes an Operand. This allows variable-length arguments arrays to be initialized, for example. - A NoUseRealAbortsScope has been added to Abort so that AssertStackConsistency can be called from PrepareForPush without introducing infinite recursion.
