Adds some necessary padding to ensure the frame is 16-byte aligned. We don't yet consider the bailout state, which will be handled separately. This patch also improves the code generated for ContinueTo*Builtin* stubs. Finally, it adds a test that checks the return value for Array.map in the case where a LAZY deopt results in a topmost builtin continuation frame - this is easy to break if the padding for the result is done incorrectly in NotifyBuiltinContinuation, but was not detected by existing tests.

This patch is a first step towards target independent tests for the CodeGenerator's AssembleMove and AssembleSwap methods. The tests on top of which this builds would only make sure that no assertions were triggered while generating moves, and that the hardware is happy executing them. We want to do more and check that the generated code performs correctly. In a nutshell, this introduces a facility that can do the following: - Setup an environment with registers and stack slots initialised with random values. - Perform a list of randomly generated moves and/or swaps on those. - Return the resulting environment. This is a first step and therefore is lacking a few things which will be implemented as follow-ups: - Support for kSimd128 moves and swaps. - Support large offsets for stack moves, as well as positive and negative. - Compare the resulting environment against the result of a reference simulation.

When starting profiling, we iterate the heap to find all existing code objects and the associated functions. The iteration tried to log the function's code if either the closure's code was optimized-but-not-deoptimized or if the optimized code in its feedback vector was optimized-but-not-deoptimized. That caused some trouble if the function's code was deoptimized but we had a valid optimized code in the feedback vector. In that case we would log the deoptimized code object from the closure, which would later crash when trying to access the deoptimization information (which we clear on deoptimization). This CL just fixes the iteration so that we do not crash. A better fix might be to log the function's code object if not deoptimized *and* the code object in type feedback vector if not not deoptimized. Or perhaps iterate optimized code objects and log those that have deoptimization information.

This is primarily needed to test D8 under ASan. ASan installs a signal handler early in the process startup to show stack traces from crashes. We need to make sure that if V8 does not handle a signal then the existing handler gets a chance. This change only applies when using V8's default signal handler. When integrating with the embedder's signal handler the behavior is unchanged.
